Re: William VanGelder, NJ/NY/Wis.
I too am a desendant of the William VanGelder you are refering to. I grew up in Dunn County, Wisconsin.
I am the GGG Grandson of his oldest son Ami VanGelder.
Ami and some of his family moved from PA to Wisconsin in about 1865 and eventually settling in Grant and Sand Creek townships in Dunn County in the 1870's. Ami's oldest son Steven VanGelder had a daughter Lula who married Alfred Matteson (later Madison).She was my dad's maternal grandmother.
I also have limited info on some other children of William, Ami, and Steven W.
I really be interested to share some information with you.
