The Ulster County Archives Dutch Records Index is an index to the English translations of the Dutch court records of Wiltwyck 1661-1709. The index was first published by the Albany County Board of Supervisors c. 1900. In 2002, the data was entered into a text searchable database by the Ulster County Archives. In 2008 a new field was added to present the entries in their entirety. These records are the earliest court and land records of Ulster County.
