We had family friends who lived in Elm Rd in Parkhall, and I can remember visiting them as far back as the late 1940s, they had two sons one of whom worked for Singer's, while the father was an upholsterer with a firm called Rowan & Boden. So my association with the area goes back a long way, but I two cannot get a handle on the Cartney's Brae, and still think it's a corruption used locally.
