Year	Event	Page	Notes
729	This is much the oldest Atholl Clan and probably dates from Pictish times. At one time, the North part of Atholl, including the greater part of this district, lay within the territory of the Northern Picts. Angus McFergus, the King of Fortrenn, or of the Southern Picts, defeated and killed the King of the Northern Picts at a battle fought at Blathvlag, near Loch Broom.		He united both Kingdoms under his rule, and he seems to have adopted the prudent course of establishing a colony of his loyal followers or Fergussons along the old boundary line. Taking the battlefield as a centre, the Fergusson country extended to the Bridge of Cally in the East, and to Cluny in Strathtay in the West. [Atholl Families]
