Thomas Smith

(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.

English: occupational name for a worker in metal, from Middle English smith (Old English smið, probably a derivative of smītan ‘to strike, hammer’). Metalworking was one of the earliest occupations for which specialist skills were required, and its importance ensured that this term and its equivalents were perhaps the most widespread of all occupational surnames in Europe. Medieval smiths were important not only in making horseshoes, plowshares, and other domestic articles, but above all for their skill in forging swords, other weapons, and armor. This is the most frequent of all American surnames; it has also absorbed, by assimilation and translation, cognates and equivalents from many other languages (for forms, see Hanks and Hodges 1988).
