The Samuel G. Drake Additions and Corrections manuscript is comprised of 121 pages of corrections, revisions, and notes Drake compiled around 1866 while he edited a new edition of Francis Baylies's 1830 book An Historical Memoir of the Colony of New Plymouth.
This manuscript is broken up into chapters one through nine (excluding chapter five), totaling 91 items (121 manuscript pages). Each chapter title page contains lists of the sources Drake referenced in that chapter. In chapter one, Drake gave his justifications for editing Baylies's work and explained the extent of his contributions; he was primarily concerned with Baylies's lack of citations and the need to update the book with new information that arose since its initial publication.
In this manuscript, Drake synthesized new secondary sources alongside his own analysis of primary sources. He kept his own notes, including family trees and short biographies of individuals. For example, on page eight Drake sketched Elizabeth Poole's family tree, and on page seven he described his difficulty finding information for her short biography. At the end of chapter one, he listed all the towns of New Plymouth and gave brief histories of them. Drake also kept detailed footnotes throughout the manuscript to keep track of his sources, add commentary, and provide clarification. In some chapters, Drake dedicated two or three pages to copies of long excerpts from other sources. For example, in chapter four, he copied primary source letters from men who lived in Plymouth in the seventeenth century, like John Cotton and Josiah Minslow.
Samuel Gardner Drake was born October 11, 1798, to farmers Simeon Drake and Love Tucke. He grew up in Pittsfield, New Hampshire, and as a young man, taught school in New Hampshire and New Jersey. In 1828, after publishing a new edition of Benjamin Church's Entertaining History of King Philip's War, Drake moved to Boston and opened the "Antiquarian Book-Store," the first of its kind in the United States. In 1845, he co-founded the New England Historic Genealogical Society. A prolific collector, upon his death in 1876, he left a collection of 15,000 volumes and 30,000 pamphlets related to early American history.
