Cresson, Martha Warner, 19th century

This collection houses documents relating to two Philadelphia silversmith families, though there is only one letter in the Richardson family series. The Humphrey family material pertains predominantly to members of the family rather than their trade. It contains two pieces of correspondence, a number of Quaker marriage certificates, recipe books, one deed of land tenancy and the last words and a memorandum of Richard Humphreys. The single item that speaks most to the trade of Richard Humphreys is a document describing the “rules to be observed in weighing gold hydrostatically.”
