My grandmother was a Schneider who also hailed from Ulm. None of the male names sound familiar, as unfortunately, I don't know of any of her brother(s) names. She had sisters that came the U.S. in the 20s, as well as at least 1 sister who remained in Germany.
Anyway, her name was Bertha and she was born in 1908. She had a sister Marie (born 1900) and another sister Josefine (sp?) but I do not know her birth year. The three sisters came the U.S. and resided in NJ.
Anything sound familiar?
