According to the notes in MacColl, _Folk Songs and Ballads of Scotland_, "John Roy of Aldivalloch was married to Isabel Stewart [on February 21, 1727). Roy was considerably older than his wife [who ran away with] David Gordon of Kirktown. She was pursued by Roy and brought back after a chase over the Braes of Balloch....
"Margaret Roy... said that the song had been made by a shoemaker living in the neighbourhood of Aldivalloch. The tune was first pubished in Walsh's 'Twenty-Four Country Dances' (1724) as Lady Frances Wemy's Reel, but is almost certainly considerably older." - RBW
