... Mattys Van Steenbergen, bp. there Mar. 31, 1678, son of Jan Jansen and Catryntje Mattysen, the immigrants — Jan Jansen van Amersfoort, or Jan Jansen Timmerman (the carpenter) as he was at first styled until the Van Steenbergen displaced both. Jan Jansen was among the very earliest residents at Esopus: in 1658 he signed the agreement to concentrate the scattered settlement and erect a stockade; in 1662 he owned a lot in the village; in 1667, at the time of the so-called mutiny, he was one of the burghers who took up arms against the English garrison; and, in fact, he figured quite extensively in the small community for years.
