| Background: A name of great antiquity in south Argyll, where at one time the chiefs were described as 'Mac Laomain Mor Chomhail Uile' - 'The Great MacMacLamon of All Cowal'. Although some believe the name to be Norman or French, the family almost certainly originated in Ulster. Logmaor, meaning, in old Norse, 'Lawman' or 'Law Giver', became in Gaelic 'Ladhman', and it is from a son of the great O'Neill princes of Tyrone that the chiefs are said to descend. The Lamonts were also one time called Macerchar, from Fearchar, the grandfather of the first Ladhman.
Variations: Turner, Turnor
