It gets mentions in the 1840s, but if it is still there, I would say it was renamed. I don't think it's Cahir Road. I suggest contacting the County Council or a local library and ask was it renamed. There are a number of streets in Clonmel that must have been renamed - O'Connell, Parnell, Kickham Streets etc..
