(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: one of the most common and widespread of English surnames, either a nickname for someone who was fond of dressing in this color (Old English grēne) or who had played the part of the ‘Green Man’ in the May Day celebrations, or a topographic name for someone who lived near a village green, Middle English grene (a transferred use of the color term). In North America this name has no doubt assimilated cognates from other European languages, notably German Grün (see Gruen).
Jewish (American): Americanized form of German Grün or Yiddish Grin, Ashkenazic ornamental names meaning ‘green’ or a short form of any of the numerous compounds with this element.
Irish: translation of various Gaelic surnames derived from glas ‘gray’, ‘green’, ‘blue’. See also Fahey.
