Harmen Schuerman is the assumed founder of the New York-New Rochelle Schuremans. He is found on Manhattan Island in 1649 in the Dutch colony of New Amsterdam. In accordance with prevailing Dutch usage his offspring for a generation or two are given the the Patrionic Harmenszen i.e: Harmens son. It is believed that he was born either in Dutch Holland or even possibly Germany, although the Dutch version is probably the correct one. A study was done by a Mr. Wynkoop who had found a reference to a Hermann Scureman who held land near Dortmund, Westphalia about 1300, but no evidence to link him to Harmen.
