This collection (51 items) is made up of financial records and correspondence related to merchants William and Robert Thompson of Thompsontown, Pennsylvania. The bulk of the collection is made up of receipts, invoices, and similar documents addressed to the Thompson brothers, particularly Robert, from 1815-1826. Most of these records pertain to purchases of various kinds of goods from merchants in Philadelphia, Pennsylvania; a smaller number of items relate to periodical subscriptions. Among the goods that the Thompsons bought were tobacco, oils, and shoes. The collection's early items largely consist of financial documents sent to William and Robert's father, also named William, as well as a newspaper clipping listing US exports between October 1800 and September 1801. A small group of correspondence includes personal letters to Robert Thompson; one correspondent wrote about the distribution of election tickets in Mexico, Pennsylvania (October 20, 1816).
