Buchanan surname meaning

Buchanan is chiefly a Scottish habitational surname from Buchanan in Stirlingshire, near Loch Lomond. The place name is traditionally analyzed from Gaelic buth chanain, “house or seat of the canon,” suggesting an ecclesiastical association. Buchanan, Buchannan, and Buchanon are spelling forms found in records, while Buchan is related geographically but is not a guaranteed variant of every Buchanan line. Place is the high-confidence catalog type because the surname’s connection with the Stirlingshire locality is strong. The precise medieval history of the place name is less certain than the geographic origin, so the literal gloss should not be over-read.
