The Van Slyck lineage is as follows:

She was for many years employed as provincial interpreter with the Indians by the government at $50 per annum. The Mohawk sachems in 1667, gave her the great island in the Mohawk River at Niskayuna. She and her husband sold the island in 1669 to Captain Johannes Clute. The Sachems also gave to her land at the Willow Flat, below Port Jackson; and at the boght on the Mohawk in Watervliet.
