My name is Ron Hentges and I am a descendant of Wilhelm also. I do no know too much about the family as I have just started to gather information for my family tree, but I will share with what I find out as I go along. My Father is Ronald F Hentges, Sr., who is the son of Nicholas Hentges. His father was Nicholaus Hentges, who was the son of Peter Hentges. Peter was the son of Mathias, who was Wilhelm's son. I did not get to know my grandparents very well when they were alive,as I grew up in CA and they lived in IA so I have been trying to gather this info for my children to keep the family history alive.
