MacAldonich
The MacAldonich Sept of the Clan Buchanan
MacAldonich (Muldonich)
This sept contains only one surname, and Buchanan of Auchmar contends that this family is descended from the second cadet of the Buchanan, lords of Lenny.
The name derives from the Gaelic name Mhaoldomhnaich, which means “Sunday’s Servant”. The anglicized name is Muldonich. Auchmar further indicates that the name became quite scarce in Scotland, primarily because the bearers were inclined to reassume the name Buchanan.
