 In 1587, the chief of the clan, "M'Lauchlane", appears on the roll of names of the landlords in the highlands and the isles, on whose land broken men dwelt.Archibald had only daughters and in turn was succeeded by his nephew Lachlan Og ("Lauchlane oig Macklauchlane his brothers sone").Not long after assuming the chiefship, Lachlan Og was forced to resign some of his lands to the chief of the Lamonts, because of the murder of Robert Lamont of Silvercrags by Lachlan Maclachlan of Dunnamuch.
