O’ Toomey, O’ Twomey, Towmey, Tuomy, Twoomy, Ó Tuama
The Ó Tuama sept was located in Co. Cork in the southern province of Munster. Twomey, and its variations, are the Anglicisation of the Gaelic Ó Tuama. The name is common in Ireland today, although it is not one of the 100 most numerous. It is strongest in its original homeland of Co. Cork, and also in the adjoining county of Kerry, where three-quarters of the Twomeys in Ireland are located.
