Re: which branch?
I'm familar with one KIRSCHKE family from Prussia. Anna KIRSCHKE was my great-greatgrandmother. She married Ernst Melcher in Prussia. The family immigrated to the United States and lived in Ohio. I believe Ernst had two brothers Gottfried and Johann. My greatgrandmother Louise Melcher was born 1869 in Prussia., Ernst Melcher was married first to Eleonore MAELZER.
