Bert - Can you provide more information? Do you know your Peter's parents names?
I have several Peter Michael's in my database, but none born in 1808 and no Phoebe Simpson. But I still think there may be a connection. My John Michael was born in MD and immigrated to Ohio. It was his grandson, Milo, that came to Indiana. John is the son of Andrew Michael I, one of 4 immigrant brothers who came from Switzerland. I don't have alot of information on Andrews 3 brothers, but their names are Christopher, William, and Nicholas. They also settled in Maryland. A cousin has traced these brothers back to 1517 and I have this information to share.
