Your reply is a gold mine for me!
I did not have the information on Joseph and Josepha and their home in Germany.
Frank Xavier's wife is listed as Katherine in the 1910 census, but elsewhere she is listed as Cresentia (sp). A name that seems to be recurring.
The 1910 census says that Katherine had 6 children, only 4 of whom were still living then. I didn't know about Mary, so she must have died before 1910.
I see that a Frank JOYCE is listed in the 1900 census in Calumet county (with a wife named "Cracynthia." I am suspecting that this is really Frank and Cresentia Joas and that the census taker that time had really bad handwriting. (I'll check when I renew my ancestry subscription.)
Do you know the sources of information for Frank Joas' parents and their other children and home in Germany?
I have been focusing on the Dauns (another family in our tree) and will be focusing more on the Joas next. And then the Hemauers!
I would love to compare notes. I have a few photos of Frank and Cresentia and some of their children.
