Thomas Brown

(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, Scottish, and Irish: generally a nickname referring to the color of the hair or complexion, Middle English br(o)un, from Old English brūn or Old French brun. This word is occasionally found in Old English and Old Norse as a personal name or byname. Brun- was also a Germanic name-forming element. Some instances of Old English Brūn as a personal name may therefore be short forms of compound names such as Brūngar, Brūnwine, etc. As a Scottish and Irish name, it sometimes represents a translation of Gaelic Donn. As an American family name, it has absorbed numerous surnames from other languages with the same meaning.
