My ggg great grandpa was
Francois Xavier Pequigney (so far as much as I can tell) who married Rosalie
Deloye and came to the U.S. in 1854. I've come in contact with someone who gave me a copy of
Francois' Birth record showing his parents as Joseph
Pequigney and Marie Anne Grisey. I don't have much info, but I'll share what I can.
