This is a created collection incorporated by the staff of the Albany Institute of History & Art. The collection consists primarily of deeds with some additional legal documents and other materials.

The Fonda Family were some of the early Dutch settlers in Albany, New York. Fonda relatives were also found in Schenectady and Saratoga counties, as well as some members becoming tenants of the Rensselaerswyck Patroon. This collection includes deeds, personal correspondence, bonds, and other legal documents.

When Stephen van Rensselaer inherited the rights to the Manor of Rensselaerswyck in 1785, a survey of the holdings was made. The holdings were divided into two parts: the East Manor and the West Manor. The East Manor consisted of the areas known as Elizabethtown (Brunswick), Phillipstown (Nassau), Roxborough (Grafton), Greenbush, Schodack, Stephentown, Middletown, and Little Hoosick. This collection contains correspondence, financial records, reports, advertisements, troop rosters, property records, inventories, and other related materials.
