Rory Dall O'Cahan was a harper and composer. He composed 'Tabhair Dom Do Lamh' (Give me your hand), and also, it is said, the Londonderry Air, which in 1851 was noted down at Limavady by Jane Ross from a traditional fiddler named MacCormick. George Petrie included the air in The Traditional Music of Ireland, 1855.
