Re: John E. Hissom (1869) & Nellie G. Reed (1883) PA
I suggest getting John's death certificate which should list his parents' names including his mother's maiden name. Check with the PA Dept of Health.
I also suggest getting his obituary which should also list his parents, any surviving siblings and hopefully exactly where he was born. Check with the Charleroi Area Historical Society to see if they can help you.
