1932. Roeliff Jansen Park, in the town of Hillsdale, New York, is named after him. The Roeliff Jansen Community Library, which also serves the towns of Ancram, Copake, and Hillsdale. Livingston Manor In 1699, Robert Livingston built the manor house of Livingston Manor at Linlithgo at the mouth of the Roeloff Jansen Kill, where it flows into the Hudson. After his death, the stream formed a boundary between the manor left to his son Philip, and the estate created for his son Robert. In 1743, Philip Livingston, grandson of Robert, founded the Livingston Forge on the banks of the Roeliff Jansen Kill at "Scotchtown", later called Ancram after the town in Scotland where the Livingstons originated. It was at the Ancram iron works that the "Fort Montgomery Chain" was forged in 1776. The chain was placed across the Hudson River near West Point between Fort Montgomery and Fort Clinton, to keep the British fleet from sailing up the Hudson. In 1854, the foundry became a paper mill. Paper manufacturer Schweitzer-Mauduit International operates a plant at that location.
