This probably doesn't help, but I'm related to Richard August Fehrman, born 4 Mar. 1929. I know he lived and grew up in Indiana until he joined the Navy.
I'm actually researching him right now, and trying to contact him. I know he has five siblings: James, Mary, Helen, Esther Jane, and John. I don't know anything further back than that...yet.
I'm going to find out where he lived in Indiana. Also, someone in his family supposedly traced their line back to Germany. When I find out more, I'll email you. If you know any more, feel free to let me know. Thanks!
