Call 'em Caughnawaga (rather than Mohawk) if allied to the French: they were Iroquois defectors who were lured off by Jesuit influences decades earlier and had to leave their home turf to move under the French wing.
As head sachem of the Iroquois Confederacy, Sir William Johnson may have had a thing or two to say about them turning coat,

not to mention the likely reaction of the Mohawk nation in general at a band that went over to their sworn enemies since Champlain's days - the home fires may have been kept burning in a less friendly way

Great looking game, again
