to be honest I'd have to talk to my gramps again the only name he gave me was his gramps and that was John. However, he did tell me to go to the mormon site. So, I did guess what they had several catherines there. But, there was one that was born in 1958. This might be your catherine. The site is www.mormon.com and then click to family history. It's pretty cool it has like 64 different entringers and when they were married and such. My gramps also told me there was a guy in Wisc. that has traced the family back quite a ways, he was gonna get me his number. As far
as where Van Croft is I don't know I couldn't find it either. But it could be close to Dubuque because my gramps said it was close to the Wisc. side cuz his dad Nicholas was born in Wisc. So we may have something here. I'm not sure how far you've traced back, I'm just getting started not knowing much about our history it's tough, although I finally got some info from my gramps which was cool. Well, I don't know if this has been any help to you at all. But, I'm trying. But, do try that mormon site (if you haven't already) cuz it's pretty cool.
