My mother's family are McSwains. I am told that the McSwains might have come from the Isle of Skye. I have also been told that McSwain name may have been McSween, McSweeny or Sweeney in Scotland before the McSwains came to America. Also I am told that the McSwain, (McSweenn, etc.) were a chip off the McDonald Clan. Does anyone have any information on this?
