Series I. Samuel Endicott Business Papers contains material from Samuel Endicott's time as a ship master, ship owner, and merchant. Some of the papers in this series are addressed to or signed by Captain M. Endicott—this refers to Charles Moses Endicott, as the materials are dated after the death of his father, Moses Endicott (1767-1807). This series has been divided into two subseries. Subseries A. Ships' Papers contains individual ships' papers. The rest of the materials are addressed to or signed by Samuel Endicott. Included in this subseries is correspondence about the building of the ship Cincinnatus. Subseries B. Correspondence and Accounts contains general correspondence about Endicott's shipping and mercantile business, receipts, and insurance papers. The correspondence to and from Captain Moses Endicott includes prices current.
