Clan MacNab: Sons of the Abbot, Ancient Lords of Breadalbane, and a Clan Rooted in Faith, Law, and the Sword
Clan MacNab (Gaelic: Clann Mhic an Aba) is one of the most ancient clans of the central Highlands, with origins that reach deep into Scotland’s early medieval past. Closely associated with Breadalbane, Loch Tay, and Glen Dochart, the MacNabs emerged from a lineage of ecclesiastical authority and early Gaelic leadership, later transforming into a respected Highland fighting clan.
Though never among the largest clans, the MacNabs possessed an old and dignified heritage, marked by scholarship, independence, and fierce loyalty to land and kin.
Their motto, “Timor Omnis Abesto” — “Let all fear be absent” — reflects a clan identity shaped by courage, conviction, and spiritual confidence.

The MacNabs are traditionally believed to descend from:
