I just read the latest WikiTree Family News about Marie Antoinette. I got curious and did the Relationship Finder and was surprised to find two bothers listed with the exact same name. This is extremely surprising, except in the case of the first child dying young, but that isn't the case here. So I expect an error has been made.
I don't have time to work on this but don't want the thread to become lost and forgotten. Would anyone be interested in helping Richard Flanagin (manager of Hillman-1528) and me (manager of Hillman-726) unravel this mystery by finding sources, etc.? It would be appreciated very much.
