Ó MAOLCHAOINE—I—O Mulqueeny, O Mulkeiny, Mulqueeny, Mulqueen; 'descendant of Maolchaoine' (servant of St. Caoine). This has been for centuries an alias for Ó Maolchaoin in the spoken language of Thomond. Thus, among the besiegers of Ballyally castle in 1641 was O'Mulqueen of Ballymulqueeny. It would appear from the Annals of the Four Masters, A.D. 1096, that Ó Maolchaoin is the original and correct form of the name. Compare with Mac Giollachaoin and Mac Giollachaoine.
