I'm interested to know if Stephan's father was Christian, and Barbli's maiden name was Griessen, as posted previously, and how was it verified? My line starts with them.

I just received a book, The Troxell Twins of Zweibrucken, authored by Thomas Eckhart, published in 1988 and that information is not in the book. It is over 1000 pages long and very interesting. I'd be happy to look up anything you think may be helpful to you.
