TWOMEY Family History
Recorded in many forms including O'Twomey, Twomey, Toomey, Twoomy, and Towmey, this interesting surname is Irish. It is a developed form of the ancient Gaelic name O'Tuama, translating as 'the descendant of Tuama'. This was a personal name probably derived from the word 'tuaim', meaning a hill or a small mountain, with the prefix O' denoting 'descendant of'. The name Twomey, usually without the prefix O, is now always associated with County Cork, and when found elsewhere it is generally spelt Toomey.
