The birth date given has been suggested as the baptism date by information given from sources; rootsweb: Early New Netherlands Settlers.
Also check out the book written by Elaine SG Kohler called the The Goewey Family.
The roots web source can easily be looked at on the internet by looking up the last name. The book is out of print but somebody must have a copy.
A church is given as to where the baptism took place. I am thinking somebody had to look at information in the church to obtain this info.
