My husband's line is the same Trautwein line you are researching. What I have been able to find is as follows:
Gustav August Trautwein was born between 1846-1848 in Bavaria. He arrived in New York Nov 7, 1866. He was married to a Francis, born 1844 in Wurttemberg. I believe they married AFTER he came to America. She has passed away by the 1900 Census. They had the following children:
Maria Trautwein b: 1869 Henry C Trautwein (our line) b: Dec 1870 John M Trautwein b 1875 William F Trautwein (your line) b: Aug 30, 1882 Frances A Trautwein b: 1886
Frances and John never married.Maria married a George C Preston. They had two girls and that is where that line has ended for me. Henry married and had two children. I found the marriage permit for William in Lorain County, Ohio. He married a Charlotte Frances Morris, born 1883 in Pennsylvania.
I have more on the Trautwein line. Please email me at LdyOfPeace@sbcglobal.net. It is nice to FINALLY find someone tracing the same line!
