When found in England the name Colman is an occupational name for a burner of charcoal or a gatherer of coal, Middle English coleman, from Old English col ‘(char)coal’ + mann ‘man’. In Ireland the name Colman is most common in counties Mayo and Sligo with significant numbers also found in Dublin and Belfast. Notable bearers include the 6th Century Irish poet Colmán mac Léníne, who was a monk, founder and patron of Cluain Uama, now Cloyne, Co. Cork.
