Jacob Janse was born about 1622 in the province of Schermerhorn in North Holland. As late as 1654, his father, Jan, was still living in the Netherlands.
In 1648, he was arrested for selling firearms to the Indians - a right apparently reserved to the West India Company. He was imprisoned and his property was confiscated. Initially ordered to be banished from the colony, he was allowed to remain but appears to have lost his property.
Jacob Janse stayed and started over. By 1652, he had married Jannetje (Seegers) Van Voorhout, the mother of his children and matriarch of the Schermerhorn family of colonial New York. In 1654, he took title to two lots in Beverwyck. He served as a commissary and later as a magistrate of the court. In 1660, he was identified as one of the principal traders in the community.
Jacob Janse was a Beverwyck/Albany fur trader and a Schenectady property holder. He was active on the Albany real estate market - owning a number of parcels in several locations. In 1679, he was identified as an Albany householder with a house on Pearl Street. However, by that time, he probably was living in Schenectady. His son, Ryer, was known in both communities and beyond!
Jacob Janse filed a will in May 1688. He may have died shortly thereafter or perhaps during the "Schenectady Massacre" on February 6, 1690. He left a large and extensive estate in Albany and Schenectady. In 1700, his administrators deeded his land in the Albany pastures to the Albany Dutch church.
