Seaman family papers, 1752-1838

Call Number: 1974.005

Extent: 0.25 Linear feet, in 16 folders in one manuscript box

The Seaman family papers (1752-1838) principally concern merchant John Seaman and Willet Seaman, though several other Seaman family members are also represented. The bulk of the collection consists of deeds and other documents concerning land transactions. Several of these deeds relate to land in North Hempstead, Long Island, acquired to establish a manufactory for woolen goods, circa 1816. Other legal documents related to this business are also in the collection, such as partnership agreements and an insurance policy. An indenture for an apprentice from the Overseers of the Poor of Brooklyn and a bill of sale for John Seaman’s purchase of an enslaved African-American also relate to the manufactory, known as Seaman and Cock (the Cock referring to partners John Cock and Townsend Cock). Other land transactions concern Seaman properties or interests on Long Island, New York City, other New York State counties, and other states. Other documents include John Seaman’s will, Seaman’s conditions for the eventual manumission of the slave he purchased, and correspondence from Willet Seaman supporting quarantine laws to prevent the spread of yellow fever.
