Thanks for your help! I had been under the impression that Peter Shaul/Challe and John Shaul/Schall were not related, but found a family tree online claiming that Peter was the son of John, so that threw me for a loop. The timing (in terms of age) is about right, but I found it odd that Peter (who I believe to be from Strasburg, France) would settle in Virginia and not New York (where John had settled). So, it makes more sense that they are not related. I have been unsuccessful in finding any of Peter Challe's ancestors.
