My Great Great Grandmother was a M. Josephine Schmidt (1840-1889), she was born in Buffalo, NY. She had both a father and a younger brother named Anton. Her father came from Germany and arrived in the 1830's. He died 06/26/1880.
I know nothing of her brother Anton. I do have additional information on her and her father. Drop me a line if you think this might be the Anton your looking for.
