From the Grier ms, as played on ‘Leitrim’s Hidden Treasure’ by the McNamara Family, who say:
“A tune with a very similar first part is known by many names including ‘The Baltimore’, ‘McCann’s Reel’ and ‘The Gasun that beat his father’; however Grier’s ‘Miss Gunning’s’ features a different and quite distinctive ‘turn’ to this tune.”
I would add ‘The Gatehouse Maid’ to that list.
