The Betaghs were one of the old Irish families transplanted from Leinster to Connacht under the Cromwellian Settlement. James Betagh of Drimhill for whom this air was composed, married Fanny Dillon, the subject of no. 37. He suceeded to Mannin after the death of her brother John Dillon, 22nd April 1731. Mannin is in the barony of Costelo and parish of Aghamore, County Mayo, a few miles north-west of Ballyhaunis.
