There are several groups of Martins or Macmartins in Scotland. The MacMartins of Letterfinlay appear to have allied themselves to the Clan Cameron in the late 14th century, and finally merged with the Camerons after the Battle of Lochaber in 1429. The MacMartins, who became a sept of Clan Cameron, are said to have been amongst the most loyal and valuable followers of Cameron of Lochiel.
