In Holland our name is also spelled te Nijenhuis and there is an internet site in Dutch that lists over 200 families with both spellings of our name. The te nijenhuis castle is in Heino Holland. Al was last seen in Southold a few months ago. good luck with your search. Len probably gave you this info but Marie van Zwam was the maiden name of our paternal grandmother and our mother's maiden name was Erika Berendsohn and her mother's maiden name was Mabel Rehr, and her mother's last name was Solomon.
