Margaret Ten Eyck was married to Baltus Coon. They lived in Ontario Co NY from their marriage in about 1813 until the early 1830's when they moved to Redford, Wayne Co. MI. Supposedly their eldest daughter was "Rene Ann" which sounds suspiciously like the "Reniam" who may have been a child of Cornelius and Mary.
The early Coons resided in Coeymans, NY in 1800.
