I am searching for the ancestors of my GG Grandmother Anna Reimschneider who was supposedly born 5 March 1840 in The Banat an 11,000 square mile area that consists of modern day Romania, Serbia, and Hungary. She married Mathias Ehrenreich and died in 1924 in Central Wisconsin, and they had 4 children.
I would appreciate any help you could give me as I know nothing more about her.
Sincerely,
Dave Weinfurtner

I believe you already used the common sources for genealogy research (ancestry etc).
Did you see this one:
