Oh well...hmmm how do I begin...
If L'Orange is one of your ancestors, it seems to be I am a relative of yours.
My grandmother sent me a lineage of her family because I am interested in history. Her maiden name was Adkisson. As far back as she could trace, the name stemmed from David Adkisson (England) who married Magdalin L'Orance (france).
I regret to inform you that I have no information before that. All I can tell you is who came after that.
If she is not an ancestor of yours, I'm sorry to have bothered you.
