The Ketelhuyn family of early Albany traces its roots to from Jochem Ketelhuyn who came to America in 1642. A native of Germany, he had been recruited for New Netherland, settled in Rensselaerswyck, and later established a home in Beverwyck. He died in Albany in 1682.
He married Anna Willems. His widow and three sons were identified as householders on the Albany census in 1697. One son, Daniel, became an early settler of Schaghticoke. His brother, one-time Albany resident David Ketelhuyn, was killed by raiders on Daniel's farm in 1711. After 1713, Jochem's third son, Willem Ketelhuyn, moved from Albany to Saratoga and died there in 1746.
