Robbert (Teuwisse) Van Deusen was born about 1665 in Claverack, NY to Teuwis (Mattheus) Abrahamsen Van Deursen and Helena Robberts.
At age 24, Robbert married Cornelia Martense Van Buren on September 22, 1689. She was the daughter of Marten Cornelissen Van Buren (1638-1703) and Marytije Quakenbosch of Rensselaerwyck Colony. (Cornelia is mentioned in her father’s will dated April 10, 1703).
On Jan. 20, 1695, Robbert was accepted as a member of the Church at Kinderhook (Holland Society Year Book, 1904, p. 10). There is a record in Albany of the transfer of two tracts of land in Claverack from Hendrick Van Renselaer to Robert Teuwis, in September 1718 (Book E p. 422, 424).
Robbert continued to live in Claverack and by June 1720, he is on the list of Freeholders.
