I am searching for info on Claus Erps. He was my great great grandfather. He had a son named John Erps and a son named Peter. John was my great grandfather. I'm sure he had other children. We always thought John came from Germany with just his children but in the last few months have come across info that he had a brother named Peter and found a picture of his father Claus in some old family pictures. It was taken in Clinton Iowa. I found out about his brother Peter by looking through some pictures with one of an Anna Erps Fitz addressed to Uncle John. Anna Erps Fitz was a daughter to Peter Erps. John and Peter both lived in McLean County, Illinois in the late 1800's. I have the pictures stated above if anyone is interested. Also have a copy of John's marriage licence to his second wife. It states that his father is Claus Erps and mother Anna Kilpin. Any replies will be greatly appreciated. Thank you!
