I don't mean to interrupt the Livaudais history but from what my former mother-in-law told me upon her research. The Delery's were associated with the Livaudais. If I can recall that far back she mentioned the Delery name came from the Livaudais name. Don't know if that helps or not. Don't know if it is correct or not. I'm just passing information on that I remember her telling me. I do recall her saying they all migrated in New Orleans with other French who came from North America (Canada, Quebec). Not to mention war time and Napoleon. Good luck in your search. I admire the Livaudais name very much.
