Thomas Mcmahon

(male) New Testament name, borne by one of Christ's twelve apostles, referred to as ‘Thomas, called Didymus’ (John 11:16; 20:24). Didymos is the Greek word for ‘twin’, and the name is the Greek form of an Aramaic byname meaning ‘twin’. The given name has always been popular throughout Christendom, in part because St Thomas's doubts have made him seem a very human character.

Irish: Anglicized form of Gaelic Mac Mathghamhna, a patronymic from the byname Mathghamhain meaning ‘good calf’. This was the name of two (unrelated) chieftain families in counties Clare and Monaghan. In northern Ireland it is sometimes Anglicized as Matthews, since Matha was the Irish form of the Biblical name.
