His maternal grandfather, Nicholas Schuyler (1691–1748), was the nephew of Pieter Schuyler (1657–1724), the first mayor of Albany, and the grandson of Philip Pieterse Schuyler (1628–1683), the Dutch fur trader who became the progenitor of the American Schuyler family.

In 1794, he corresponded with James Madison regarding a letter of introduction for Robert S. Van Rensselaer, the son of his brother Philip, on his trip to Europe, at which time he met with members of the extended Van Rensselaer family in Holland.

United States Congress
Van Rensselaer was elected as a Federalist to the Seventh United States Congress, taking his seat on March 4, 1801, during the first Congress that met in Washington, D.C., as the previous congresses had met in New York and Philadelphia.
