Dexter

(male) Transferred use of the surname. Although this is now a male given name, the word that gave rise to the surname originally denoted a female dyer, from Old English dēag ‘dye’ + -estre, feminine ending of agent nouns. However, the distinction of gender was already lost in Middle English. The name coincides in form with Latin dexter ‘right-handed, auspicious’, and may sometimes have been chosen because of this.
