In the late 17th century, two New York City merchants, Francis Rombout and Gulian Verplanck, bought , most of it in the creek's watershed, from the local Indians. Verplanck died before the transaction could be finished, and with his share divided among his heirs the land became known as the Rombout Patent. In 1709 his daughter Catheryna and her husband Roger Brett became the first European settlers in the Fishkill valley. She administered the subdivision and sale of the patent lands from her house, which still stands near downtown Beacon, the oldest continuously occupied house in Dutchess County. They also built the first mill on the creek in 1717.
