TREANOR Family History
This unusual and interesting surname can be either English or Irish. Recorded in a wide variety of spellings including Trainer, Trener, Traynor, Trinor, Tronor, Trynor, Triner and Trinner, it has at least two possible originations. The first is from the pre 7th century Olde English 'trayne' meaning to trap or snare, and hence a name for a hunter. Secondly if originating in Ireland, it may have the same origination from English settlers, or it may derive from the pre 10th century Gaelic Mac Threinfhir, meaning " the son of the champion".
