Mike, I just started working on the Gentz's, but I did find a Mathias & Mary Gentz and their son John Gentz and they settled in Pewaukee, Waukesha Co., WI. John was born in Prussia. They came here in 1847. Got this info from a researcher at the Waukesha, WI. library. I haven't found a connection between my Gr. Grandfather Edward Gentz who was born in Waukesha, WI. and the above Gentz's but since they might of come from Prussia I figured I'd pass the info along to you.
