I have never heard of Michael (perhaps it was in someone else's posting you're referring to), but my great-great (great)grandather was F.F. Schnitzer, married to Anna Maria Keller. His son was F.F. the architect. We are definitely related! I have so much information, includng pictures of F.F., you would not believe it. Please reply to me at firstname.lastname@example.org. This is great news!
