In researching my father's family links back to the "original" TenEyck in the US (Coenradt, who arrived in New Amsterdam c/a 1650 as a sponsored shoemaker for the Dutch West India Company)I was unable to find any "paper trail". Same is true for all other known TenEycks whose family roots came through Rockland County. (Lots of info available for TenEycks anchored in NYC, Albany,NY area, and NJ--but zero for Rockland)
