From Fiddlers Companion:
BRECHIN CASTLE. AKA and see "Miss Douglas of Brigton," "Lady Harriot Hay." Scotland, Strathspey. B Flat Major. Standard. AAB (Gow, Hunter): AABB (Honeyman, Kerr's, Skye): AABB' (Athole). The melody was known by the alternate titles until Gow published it under the name above in his 1st Repository (1799). The name Brechin is purportedly derived from Brychan the son of Brychan, who moved to the area from southern Wales. The Round Tower at Brechin probably dates from around c. 990 when Kenneth II took control of the area. Subsequently, around 1150, a cathedral and bishopric were founded there. Hunter (1988) notes that Brechin Castle is the seat of the Earls of Dalhousie. Gow (Complete Repository), Part 1, 1799; pg. 32. Honeyman (Strathspey, Reel and Hornpipe Tutor), 1898; pg. 28.
