Kiliaen Van Rensselaer (d.1646) received the family patroonship along the Hudson River near what later became Albany, New York, but it is doubtful if he ever visited New Netherland. He lived in Amsterdam, Holland, The Netherlands, and directed the establishment and management of the patroonship. His son, Jeremias Van Rensselaer, replaced a temporary administration under his brother Jan, and Jeremias married Maria Van Cortlandt in 1662. Descendants and relatives lived in New York, Louisiana and elsewhere. Includes ancestry and genealogical data in The Netherlands.
