[MadManDan]

I believe Jourdan is a French name, which is probably where they learned blacksmithing also.

Not quite French ~ I'm giving it an independent origin since the European name of the progenitor of the family is inpronouncible in Iriquois.

The Iriquois regularly encouraged European settlement within their country, and the Oneida and Onondagas were quite noteworthy for the percentage of their populations who actually were purely European or mostly European in origin.

The leader of the Mohawk (for the Brits) during the Revolution actually was mostly European.
