Representatives had been elected in April 1806 to a term in the 10th United States Congress beginning on March 4, 1807.

David Thomas had been elected New York State Treasurer in February 1808, and had resigned his seat, leaving a vacancy in the former 12th District.

After some time both terms got more and more confused, and sometimes used together as "Democratic Republicans" which later historians have adopted (with a hyphen) to describe the party from the beginning, to avoid confusion with both the later established and still existing Democratic and Republican parties.

Nathan Wilson took his seat in the 10th United States Congress on November 7, 1808.
