Robert P Charters, was a house builder who built, inter alia, Gortland Park and Gortland Avenue and other developments at Gilnahirk. The ground on which Charters Avenue was built was 'left over" from one of these developments. The houses there were built in the mid 1960s by Robert’s brother, William Charters, who was also a builder. In view of this local people called it “Charters Avenue”, the name stuck and it is now officially known as Charters Avenue. (Source of information: Robert S. Charters, son of Robert P Charters and nephew of William Charters).
This entry requires further research to establish when it was officially named Charters Avenue.
