I now have the information that you may be looking for.By the way, the Andre Gascho that you had referred to was a brother to my 4th great-grandfather Joseph Gascho, who had married Catherine Zwalter.Brothers Joseph and Andre had married sisters.As you had mentioned, Andre was married to Anne Zwalter.Their parents (my 5th great-grandparents) were Francois and Anne Chraque (Schrag).
The Mary (b. Dec. 25th 1833 in Probfeld, Bavaria) that you were referring to had these brothers and sisters in order of age: Anna, Magdalena, Joseph, Barbara, (Mary), Christian, John, and Andrew.
Mary was married to Christian Steckly (b. Feb. 8th 1829 in Xouxange, France, d. 1906 in Nebraska).They had these children in order of age: Katherine, John, Fanny, Mary, Barbara, Joseph, Magdalena, David, Anna, Christian, Lydia.
I have a lot of info.If you are interested, please give me your email address and I will scan what I have and send it to you.
There is a genealogy book on the descendants ofJoseph Gascho and Magdalena Ingold that does exist.I had seen a copy of it in the library at Conrad Grebel College in Waterloo, Ontario a number of years ago.
