Our goal is to have as many people with some form of the Van Gilder surname Y-DNA tested as possible to figure out which groups of Van Gilders in the United States are related to one another.  This project will benefit all descendants whether they are from an actual Dutch Van Gilder family or descend from a Native American man who took the name at some point.  We will link up different groups of Van Gilders who have the same Y-DNA.  

Surnames:
Van Gelder, Van Gilder, Van Guilder, Van Galder, VanGelder, VanGilder, VanGuilder, VanGalder, Vangelder, Vangilder, Vanguilder, Vangalder, van Gelder, van Gilder, van Guilder, van Galder, Gelder, Gilder, Guilder, Galder, etc.
