The Irish name Mulqueen is derived from the native Gaelic O'Maolchaoin and O'Maolchaoine Septs. These Sept names are derived from Gaelic phrases meaning 'gentle chief' and 'servant of St. Caoine' respectively. Mulqueen and the variant Mulqueeny can be found mostly in Connaught where the town of Ballymulqueeny still exists. County Clare was the settlement point.
