 The stronghold of these early Galbraiths was on the island of Inchgalbraith which is located on west side of Loch Lomond about 2 miles south-east of Luss.The heraldist Iain Moncreiffe of that Ilk speculated that the Arms of the Galbraiths—which bore "three bears' heads"—may allude to the British name "Arthur" that is thought by some to mean "bear".The man who is considered to be first chief of Clan Galbraith was Gilchrist Bretnach who married the granddaughter of the first Earl of Lennox.
