I have a problem with more than just her birth date, but also the fact that her Farther, Garret, profile says he Emigrated to America (United States) about 1662/63 and Lived in what is now New York City between 1663 and 1690. If that statement is true she couldn't have been born in the Netherlands, but NY.
Plus they have her date of birth as Mar 1673 and her sisters as Sep 1673. Not sure that can happen. Alot more research needs to be done on the DeWess family, IMO.
