Thank you Annie. I have all of this already. The passenger list person you listed is not Mary Heinzmann. Turns out Mary (Marie) came to the U.S. with her brother (Matthew Heinzmann) and her illegitimate son (Johan Matthew Heinzmann). A month after they arrived she married Matthew Schwab in CT. My thought is that Matthew Schwab was John (Johan) Matthew Heinzmann's biological father.
I have hit a brick wall trying to find Matthew Schwab's parents and the town he was born in. I don't think he was born in Nufringen as Mary was.
Thanks for your help. It is much appreciated. Lynn
