Yes, I do have that, but that is the earliest reference I've been able to find. There are a few different people in that area of the country at that time with names similar to Christian Krepps so I'm only guessing that that's him. I did some more research this morning on some people not in my direct line and did manage to find the elder Christian in the 1850 census in Beaver, PA, which gave me a more definitive age (72). According to that census, he was born in France, not in MD. However, even substituting that information for what I had before hasn't yielded any further information as to his lineage.
