Gille Chlerig,1 also Gillocheri 2 or Gillocher, Gillocher or Gylocher is a Gaelic name attested only in a Latin source, a 13th-century forgery designed to advance the cause of Scottish independence. The name is highly corrupted, and therefore the name and meaning is unclear. Gille Chlerig is not known in any capacity other than being father of Morggán, but most scholars seem to be comfortable accepting him as the Mormaer or Earl of Mar who preceded his son Morggán.
