These names are synonymous with the name Buchanan which is of the territorial derivation. 

The early chiefs were known as MacAuselan, MacAslan etc. an allusion to their descent from Anselan Buey O’Kyan alleged to be an Irish prince. This has since been disproved through YDna so the origin may be unknown. 

The MacAuselan first actually to be recorded was Malcolm, Steward to the Maldouen, Third Earl of Lennox during the reign of David II (1124-1153 A.D.)  Malcolm may have inhabited land in Glenduglas on Loch Lomond as well as in Luss, all on the western shore.  This Malcolm is believed to have been the Baron MacAuselan from whom the bearers of the patronym are descended. The seventh Laird of Buchanan, Gilbert, was the first to assume the surname of Buchanan.
