Plans to build a street named Quinton Street are mentioned as early as 1882 as part of a development between Cregagh Road (now Woodstock Road), Willowfield Street and Castlereagh Road. However, Quinton Street as actually built is on the east side of Castlereagh Road.
Quinton is a place-name that occurs in several different counties in England. There are also several instances of Quinton Road / Street in England. It therefore seems likely that the name is not rooted in Belfast.
Resolved that on the application of the owner, Mr J. D. Dunlop, new streets on his property situate off Castlereagh Road be named ‘Glenvarnock Street’, ‘Lambourne Street’, 'Wayland Street' and ‘Quinton Street’ and that he be requested to submit another name instead of Brenda Street, as there is already a street of almost similar name in the city.
