I have a document dated during the French Colonial period of Louisiana. It's for a relative of mine (Claude Joseph Grossourd (sp?) and appears to be a discharge paper from "Compagnies detachees du Regiment Suisse Dhallwyt (sp?) de la Marine. I assume this relative was in a Swiss unit supporting the French garrison of Louisiana.
I can't find either this Surname or this unit and their origin anywhere. Is there anyone with knowledge of either this unit or this surname?I think this surname became Gros in Louisiana, but have no way to determine that either.
