Hello! I've just come across this name in my family tree and find that there's very little on line! The name is that of my paternal great great grandmother - Catherine Geppel. She is listed on her son John's death certificate (died in 1919) as having been born in Germany. Her husband was Jacob Schwartz, also born in Germany. Her son was born in 1859 in Philadelphia, PA so she emigrated sometime prior to that date and must have been born sometime between 1819 and 1839.
If you know anything at all about this woman or, just generally, about this surname, I'd love to hear from you and would be most grateful! Thanks. Pat
