This collection is made up of correspondence, documents, and other items related to New Jersey politician Jonathan Dayton; his son-in-law, Oliver Hatfield Spencer; and Spencer's son-in-law, William Nelson Wood. The materials concern politics, finances, property, genealogy, and other subjects.

This collection is made up of 3 linear feet of correspondence, documents, and other items related to New Jersey politician Jonathan Dayton; his son-in-law, Oliver Hatfield Spencer; and Spencer's son-in-law, William Nelson Wood. The materials date between 1764 and 1892, and they concern politics, finances, property, genealogy, and other subjects. The collection is arranged into groups of Jonathan Dayton papers, Oliver Hatfield Spencer papers, William Nelson Wood papers, and Spencer and Wood family papers.

The Jonathan Dayton Papers are divided into 3 subseries. The Jonathan Dayton Correspondence subseries is made up of Dayton's incoming (over 310 items) and outgoing (approximately 55 items) letters between 1780 and 1824. Dayton corresponded with family members, professional acquaintances, and political figures. Many of the early letters pertain to Dayton's congressional service, national and local politics, and personal matters. A group of 14 letters from 1807 concern the Burr Conspiracy and its effects on Dayton, who was imprisoned in connection with the incident. Some of Dayton's correspondents discussed Native American relations and the Northwest Territory. Others provided family news from Cincinnati and commented on legal and financial issues.

The Jonathan Dayton Financial Documents (15 items, 1774-1830) consist of receipts, accounts, and account books, pertaining to real property, taxes, and other financial matters. The 2 account books (1792-1793 and 1823) concern shipping costs, livestock, debts, and real property. A copy of Gaine's New-York Pocket Almanack for 1775 contains an unidentified writer's manuscript notes and financial records kept between 1775 and 1779.

The Jonathan Dayton Legal Documents (76 items, 1764-1821) include deeds for property in New Jersey, contracts, records pertaining to court cases, and other items.

The Oliver Hatfield Spencer series , divided into subseries of Correspondence (5 items) and Documents (13 items). Letters to Spencer, dated 1820-1821, concern his claims against the estate of "Mr. Evans." Other items, dated between 1802 and 1856, include certificates, deeds, Spencer's will, receipts, and a military commission. These documents relate to Spencer's medical career, his work for the New Orleans Board of Health and the Medical Board of the State of Louisiana, and his memberships in the Medical Society of Philadelphia and the Chemical Society of Philadelphia. Three later items pertain to his estate.

The William Nelson Wood series includes Correspondence (19 items) and Estate Documents (41 items). James Cook informed Wood of his brother's death in a letter dated February 21, 1831. The bulk of the remaining correspondence, written from 1853-1854, concern the estate of Clement Wood, a resident of England. Two letters by Luigi Palma di Cesnola (June 27, 1864, and July 7, 1864) report the death of Wood's son Oliver during the Civil War and discuss the Battle of Trevilian Station. A subseries of Estate Documents consists primarily of claims made against Wood's estate following his death in 1865.

The Spencer and Wood Family Papers (153 items) consist of letters, documents receipts, genealogical notes, autographs, an invitation, and an essay related to the descendants of Jonathan Dayton, Oliver Hatfield Spencer, and William Nelson Wood. Correspondence, Documents, and Receipts include incoming and outgoing letters related to members of the Dayton, Spencer, and Wood families, often concerning family news and legal affairs. The series includes Genealogical Materials for the Dayton, Williamson, Halstead, Spencer, and Ogden families. Eighty-seven Autographs cut from letters include signatures and handwriting of prominent individuals in the late 18th and early 19th century. The final items in the collection include an essay description of Jesus Christ (with an 1847 song "The Hieland Laddies' Farewell" written on the back) and a vellum invitation for Edward Meeker Wood to attend The General Society of the Cincinnati and the Sons of the Revolution commemorative event for the death of George Washington, held on December 14, 1899.

The King family papers document the business activities of the King brothers, three of whom worked as traders with Russell & Company in China in the mid-19th century, and the subsequent institutionalization of William King.

The correspondence series contains 69 letters. The earliest are from William King to his brothers, while in China in the late 1840s. They mainly concern trade conducted by Russell & Co., and frequently contain figures and purchasing instructions. During early 1850s, King writes several letters from New York discussing stocks and business matters.

A major shift occurs in the mid-1860s, when the most frequent topic of correspondence becomes William King’s mental health. One letter, from N.P. Russell, urges David King, Jr., to make William “obedient…to the stronger will of others” or else face “a public disgrace” and “wreck of both mind and frame” (October 16, 1864). Letters document several unsuccessful attempts to keep King’s behavior in check, including instructions from a physician to King, prescribing a healthier lifestyle (July 21, 1865), but by July 1866, the King brothers were corresponding with the McLean Asylum, where William had already arrived.

The few letters between 1867 and 1895 reveal more about King’s condition, mentioning “delusive fancies,” “acts of violence,” and a belief that “other patients are here as spies upon him” (July 29, 1870). Reports from doctors and friends during this period document a gradual worsening of King’s health and faculties. No correspondence documenting the legal case with Eugenia Webster Ross survives. The two folders of undated correspondence contain several letters in French as well as some unusual ruminations on women, night, and other topics, which appear to be in William King’s handwriting, and may have been addressed to a female love interest.

The documents series contains 36 items, including legal documents such as David King, Sr.’s will, tax documents, land indentures, and lease, loan, and rental papers, dating from the 1840s to 1900. Of particular interest is a printed 1893 Massachusetts Supreme Court record concerning William King’s condition, and Eugenia Webster Ross’ petition.

The Laidley family papers consist of letters written by members of the Laidley family regarding family news, politics, and life in the military. The collection also contains fiction written by William Sydney Laidley, a travel journal, legal documents, photographs, and genealogical materials.

The Laidley family papers are comprised of letters, a travel diary, miscellaneous documents, creative writing, genealogical materials, business cards, newspaper clippings, and photographs.

Correspondence: The bulk of the letters are from Theodore T.S. Laidley to his father, John Osborne Laidley, between 1838 and 1861. The collection also contains letters from Theodore to his brother William Sydney Laidley, and letters from various friends and family members, including Amacetta Laidley and George W. Summers, to John Osborne Laidley.

Theodore's early letters describe his life at the United States Military Academy at West Point. After graduating from West Point, Theodore spent time at the Watervliet Arsenal near Troy, New York. He wrote to his father monthly about military life, his enjoyment of New York State, and his health. Theodore took an interest in politics, and was very much concerned about bills, policies, and appointments that he felt were detrimental to the future of the army.

Letters from Theodore contain news about his family, his wife's family, and their health. He also wrote to his father with advice about his siblings. Fewer letters exist from the other Laidley children, and Theodore refers to them being infrequent correspondents. Amacetta did write her father from Washington, recounting politicians and writers she had met. Amacetta's husband, George W. Summers, wrote to John Osborne Laidley about legal matters and his future in politics. Laidley's friends and children wrote frequently about faith and church matters. Following John Osborne Laidley's death in 1863, the bulk of the letters are from Theodore Laidley to his brother, William Sydney Laidley.

Diary: The travel diary is the record of an unidentified family member's journey from Charleston, West Virginia, to Cincinnati, Ohio, in 1879. It contains several pencil drawings including sketches of bridges, a ship, the Chesapeake Bay, and a chandelier.

Documents: The miscellaneous documents consist of receipts, a bill of sale, and a deed.

Creative Writing: The creative writing series contains two poems and a short novel of the Civil War written by William Sydney Laidley.

Personal and Genealogical Materials: The personal and genealogical materials consist of Thomas Laidley's report cards, including some from West Point, a large family tree, information about individual family members, and records of births, deaths, and marriages.

Business Cards: The business card series is made up of the business cards of Theodore Laidley and William Sydney Laidley. William Sydney Laidley's business card features a pencil drawing of an infant on the reverse.

Newspaper Clippings: The collection includes two newspaper clippings. The first is a report of the sinking of the steamer Sultan and the death of Sarah Laidley Poage. The second is a report of a trip to Europe by a member of the Laidley family.

Photographs: The photographs series is composed of three photographs, including two of William Sydney Laidley and one of an unidentified member of the Laidley family.

The Langstroth Family papers document the activities and relationships of several generations of the Langstroth family, originally of Philadelphia, including the founding of several schools for women and African Americans, the experiences of a patient the Friends Asylum, and service in the Civil War.

The correspondence series comprises 600 items covering 1831-1955, and sheds light on the personal lives, careers, and activities of several generations of the Langstroth family. The bulk of the earliest letters, dating from the 1830s, are from Catharine Langstroth to her father and siblings. These letters concern the death of her sister Sarah, financial issues, and the health of several family members, including Margaretta, and refer to temperance (July 20, 1835 “It affords me much pleasure to know that you gathered in your hay on temperance principles”) and religious study. One letter of particular interest is dated January 3, 1839, and was written by Margaretta during a stay at the Friends Asylum in Philadelphia. It describes a harrowing series of treatments for unspecified mental problems: “My head has been cut open to the bone for 3 inches; and large [peas?] inserted; a lead placed over the slit and on the top of this a bread & milk poultice has been applied for two months… My hair has been shaved at least 6 times; and three times since the head was opened.” Margaretta also described the Asylum’s lectures, food, and other patients (“only deranged at intervals”).

Letters from the 1840s and 1850s were written by a variety of family members and document the founding of Mount Holly Institute for Young Ladies; the courtship of Thomas Langstroth, III, and Mary Hauss; and a range of religious attitudes, from Margaretta’s intense piety to Thomas’ doubt (December 12, 1853: “most all the young men in our church just before they got married have made a profession of religion, and how have they turned out! Look at them one half are as bad as they were before: but I have no right to judge.”). In early 1855, Margaretta wrote a series of letters from near Pine Bluff, Arkansas, describing her efforts at religious and educational outreach to slaves, for whom she felt sympathy (February 7, 1855: “Slaves! poor slaves! how my heart bleeds for them, they toil from night to morn, from morn to night--live and die here without knowledge enough to save the soul.”).

Little documentation of the family exists from the Civil War period, despite Edward and Thomas’ service on opposite sides, but Edward’s letter to Margaretta of July 14, 1865, indicates a rift between himself and his sisters, perhaps arising from his joining the Confederacy. Letters of the 1860s and 1870s are mainly incoming to Margaretta and concern teaching, finances, and advice. A number of letters to Thomas from the 1880s contain information about his brother Edward’s health. Approximately 25 folders of letters date from the 20th-century and were written between Hugh Tener Langstroth, his sister, Sara Paxson, and other relatives. These concern travel, social visits, health, and business matters.

The financial and legal documents series consists of 124 items relating to the Langstroth family, covering 1778-1913. It includes wills, records relating to milling, land indentures, an account book of 1814-1817 kept by Thomas Langstroth, Jr., paperwork related to loans, and other materials. Some materials relate to the bank failure which forced Langstroth to sell his mill in 1836. Only 15 items date from 1851-1913.

The diaries and journals series represents six volumes and a few fragments, covering the 1830s to the 1860s, all written by Margaretta Langstroth. The volumes dating from the 1830s contain biographies of historical figures and may have been used in school. Subsequent diaries recorded daily entries of varying length, covering parts of 1864-1868. The 1864 volume includes Margaretta’s memorials of deceased family members and is thus a good source of genealogical information. More commonly, her entries describe daily activities, religious meditations, and frequently seem to reflect a fragile mental state, as in this exceprt of April 15, 1865: “Abraham Lincoln shot in the Washington Theatre Secretary Sewar [sic] had this throat cut I hope Edwar [sic] has no hand in this what makes me fear that he had” or an entry of June 19, 1866, describing the death of a robin: “I felt very badly cannot describe my suffering poor bird…read hymns as it was dying wondering if it would live elsewhere[.] In bed all day so distressed so wretched…” In a number of passages, Margaretta noted the Sunday School classes that she taught, and commented on the number of students and the subjects of her lessons.

Collection of bound and miscellaneous manuscripts relating to the history of Latin America between 1518 and 1882. These materials pertain to laws, religious doctrines, indigenous cultures and interactions with Europeans, city ordinances, land holdings, and other subjects. In addition to this finding aid, the Clements Library has created the following descriptions of each volume in the collection: Latin America Collection: Volume Descriptions.

The Latin America collection is made up of 57 volumes of miscellaneous items related to New Spain, Mexico, Peru, and Guatemala. The items span from 1518 to 1882. The materials came to the Clements Library from multiple dealers and donors between 1928 and 1951. The New Spain series is made up of volumes that broadly cover the areas under Spanish control in Latin America. The Mexico, Peru, and Guatemala series is made up of materials that specifically address each of those areas. Topics addressed in the letters and documents include laws, religious doctrines, indigenous culture and interactions with Europeans, city ordinances, land holdings, viceregal matters, and many other subjects. Of particular note is a 1760 manuscript copy of a 1587 original of three religious dramas in the Nahuatl language. In 2023, an 1822 contemporary manuscript copy of Manuel de la Barcena's Manifiesto al Mundo: La Justicia y Necesidad de la Independencia de Nueva-España was added to Volume 38.

In addition to this finding aid, the Clements Library has created detailed the following descriptions of each volume in the collection: Latin America Collection: Volume Descriptions.

The Le Maire Family Papers are made up of 325 letters and documents largely pertinent to this Dunkirk, France, family's coffee and cocoa plantation near Jérémie, St. Domingue. The collection focuses on the period immediately preceding the Haitian Revolution and years following the conflict, though a group of letters date from the period of the revolution.

This collection consists of a diary (108 pages), a school notebook (111 pages), and a scrapbook (approximately 15 pages) related to Levi C. Wade, a Massachusetts lawyer and director of the Mexican Central Railway Company in the late-19th century. The diary is an account of Wade's visit to Mexico City in the late months of 1879 to win governmental support for his proposed railway, and a record of his observations on contemporary Mexican politics. The school notebook contains Wade's lecture notes from the Newton Theological Institute and from his law studies. The scrapbook holds material related to Wade's death and to his sons, among other subjects.

This collection contains a diary (108 pages), a school notebook (111 pages), and a scrapbook (approximately 15 pages) related to Levi C. Wade, a Massachusetts lawyer and director of the Mexican Central Railway Company in the late 19th century.

Levi Wade kept a Diary while traveling to and living in Mexico City between October 3, 1879, and December 11, 1879 (108 pages). After leaving Boston for New York City on October 3, he embarked for Veracruz, Mexico, onboard the steamer City of Alexandria. He discussed several aspects of his life onboard, such as his leisure activities, other passengers, the weather, and stops at Havana, Cuba (October 9-10), and Campeche, Mexico (October 14), before reaching Veracruz on October 16. While on shore at Havana, Wade described the city's architecture and people, which he later compared to Veracruz, a city that had experienced recent political upheaval and executions. The day of his arrival, he and his traveling companion boarded a train for Mexico City, arriving on October 17. Wade remained in Mexico City until at least December 11, devoting most of his time to political maneuvering and attempts to secure the government's approval for his proposed central Mexican railway. He often remarked about the structure of Mexican politics and about specific events that occurred during his stay in the country, often providing his own commentary. Wade frequently reported on his efforts to secure government support, and met or corresponded with several prominent politicians, including President Porfirio Diaz and members of the Mexican Cabinet. Along with his observations about the country's political system, Wade also wrote about the country's people, food, and customs, as well as the foreigners he met during his travels. Though he often mentioned his frustration with the lack of progress regarding his proposal, by December 11 he seemed optimistic about eventual success, having received the president's support and that of other high-ranking officials.

The School Notebook (111 pages) holds 94 pages of notes from lectures Wade attended while studying at the Newton Theological Institute (1866) and approximately 16 pages of legal forms and similar notes pertaining to his legal studies (1871-1872). Wade studied the Biblical Gospels with Horatio B. Hackett (pp. 1-56), Christian ethics with Alvah Hovey (pp. 57-90), and symbology and Christian doctrines with an unnamed instructor (pp. 91-94). The section on the Gospels contains lectures on the differences and similarities between the four books, as well as on the life and ministry of Jesus Christ. "Events in Galilee Till the Second Passover," (pp. 32-41) speculates on the locations of various Biblical events, and includes verses clipped from a King James Version of the Bible. Other lectures are about Christ's final days, crucifixion, and resurrection. Alvah Hovey's lectures focused on Christian ethics, and its practical applications. The final section of religious lecture notes concerns Christian creeds, symbolism, and doctrinal sources. The final portion of the book (pp. 96-111) contains copied examples of legal forms and similar information about legal practice, notes on real estate, and a list of books Levi Wade had read (p. 97).

A Scrapbook (approximately 15 pages), complied by an unknown creator, consists of programs, reports, and newspaper clippings from 1879 to 1902. The first page shows clippings from the Westminster Review related to Levi's sons, Levi, Jr., and Robert, and many of the following pages contain programs for concerts or other events. The two printed reports are the "9th Annual Report of the Board of Directors of the Mexican Central Railway Co." (December 31, 1888), and a report from the president of Bowdoin College (1898-1899). Additional newspaper clippings are about a variety of topics, such as poetry and the development of transportation. Many relate to the death of Levi C. Wade, including an obituary from the Newton Graphic (March 27, 1891), a report on his funeral, and tributes.

The Litchfield-French papers contain correspondence and documents related to the Civil War service of Allyne C. Litchfield and the Spanish-American War participation of his Litchfield's son-in-law, Roy A. French.

The Litchfield-French papers consist of 414 items ranging in date from February 15, 1862, to 1918, though the bulk of the collection lies between 1862 and 1899. The collection includes 335 letters, 60 documents, and several clippings, photographs, and receipts. Approximately 280 of the letters cover the period of Allyne Litchfield's Civil War service, including letters from Litchfield to his wife, letters among and between the Litchfield and Carver families (especially Lysander Carver and Susan Carver), and other correspondence pertaining to Allyne Litchfield. Roy French either wrote or received around 65 of the letters, primarily during the 1890s.

Between early 1863 and Litchfield's capture in March 1864, he wrote near-daily letters to his wife, describing movements, battles, and camp-life, and expressing his love for her. On May 9, 1863, he described the exhaustion of cavalry forces, led by George Stoneman, to whom the 7th Michigan sent reinforcements: "you can imagine perhaps the condition of men and horses after being saddled and ridding [sic] for 7 days. One can see the bare bones on the backs of some of them." His letters of July 6 and 7, 1863, are almost entirely devoted to his experiences at Gettysburg, and contain his accounts of his horse falling on him after it was shot in battle, and his regiment's extremely heavy losses. At times, Litchfield's correspondence also reveals his managerial side, as in a letter from Michigan Governor Austin Blair, recounting an anonymous complaint about "Col. Man" (almost certainly Col. William D. Mann) and requesting Litchfield's perspective on the matter (June 18, 1863). Also of interest is a letter of December 19, 1863, in which Litchfield detailed having dinner with 24-year old George Armstrong Custer and expressed his admiration for him.

After his capture, Litchfield wrote infrequently; however, ,in his letter of March 16, 1864, he described his conditions: "I have been kept in an 8x12 feet cell… 4 negro soldiers with us." More prevalent are letters to Susan Litchfield from family members, expressing support for her and suggesting solace in religion. The few letters to his wife, Litchfield generally communicated an optimistic attitude and gratitude for his good health, as in his letter of November 4, 1865, from prison in Columbia, South Carolina: "I have shelter, still retain my old overcoat and have plenty of blankets, which I am sorry to say is not the case with most of the officers."

Very little correspondence exists between 1865 and 1893. In the latter year, Roy A. French began writing a series of letters to his relatives, which became more frequent when he joined the military. In 1898, he commenced writing to his future wife, Almira "Myra" French (daughter of Allyne and Susan French). He described "monotonous" camp life at Camp Townsend in Peekskill, New York (July 15, 1898), his voyage to Puerto Rico on the Chester, during which he was very seasick, and his observations of Ponce, Puerto Rico, including the people, their modes of transportation, and the wild fruits that he saw (July 15, 1898).

On September 25, 1898, he wrote from "Camp Starvation" ("that is what the regulars call this camp because we are fed so poorly"). He reported prolonged health problems, from which he would die in 1911.

The 60 documents and miscellaneous items include newspaper clippings, military and family documents (such as a will, a passport, and a wedding invitation), a wallet, and a metal nameplate. Of particular interest is a manuscript copy of a letter of recommendation for Litchfield by George A. Custer. The copy is dated February 24, 1881. Other items document Litchfield's service in India to some extent.

This collection is comprised of five volumes of copied passages from magazines, newspapers, speeches, and other literary sources, on subjects such as religion, history, philosophy, economics, science, and fiction. Also included is a handwritten essay on "Physical and Moral Courage," and a Wilmington, Delaware, bond related to the estate of Edwin A. Wilson, April 1, 1859.

Also included is a handwritten essay on "Physical and Moral Courage," and a Wilmington, Delaware, bond related to the estate of Edwin A. Wilson, April 1, 1859.

The creator of these commonplace books, writing in a dense, consistent hand, recorded passages from a wide range of authors that include Plato, Aristotle, Tertullian, Geoffrey Chaucer, Martin Luther, Nathanial Hawthorne, Charles Dickens, Baden Powell, Oliver Wendell Holmes, and others. Publication notices and excerpts of literary reviews are frequently noted. Passages often include references to the author or the publication source. Latin, Greek, and Hebrew words or lines periodically appear as well.

Included in the collection is a handwritten essay, titled, "Physical and Moral Courage", exploring these ideas within the framework of Ancient Spartan society, as well as their relationship to the legacy of Julius Caesar. A partially-printed bond dated April 1, 1859, from Joseph C. Seed to David Craig and William Tatnall in Wilmington, Delaware, pertains to the estate of Edwin A. Wilson.

The Louis A. P. Bouan collection is made up of journals, letters, and documents, many of which pertain to Bouan's service as a military engineer in the French army during the late 18th century.

The Louis A. P. Bouan collection (22 items) is made up of journals, letters, and documents, many of which pertain to Bouan's service as a military engineer in the French army during the late 18th century.

The Journals series contains 2 items. The first is pages 5-6 of Bouan's journal about his experiences during the Siege of Schweidnitz (now Świdnica, Poland) in 1762. The second, entitled Journal du Siege d'York en Virginie (7 pages), is a daily account of events around Yorktown, Virginia, from September 28, 1781-October 18, 1781. Bouan recounted the activities of American and French forces and reported Charles Cornwallis's call for a ceasefire. The journal also records the number of British troops present at the surrender.

The Correspondence series (12 items) contains letters to Bouan from French courtiers, such as the Count of Saint Germain and "Montbarrey." Most of the correspondence pertains to Bouan's service as a military engineer. The Documents (7 items) also relate to aspects of Bouan's military service, as well as to that of his father, Louis Joseph Bouan. The series includes documents emancipating Louis, François Cecile, and Julienne Anne Bouan from their father (January 23, 1771), and certifying Louis Bouan's successful completion of engineering examinations (January 1, 1776).
