Sulby Road in Cashmere – First appears in street directories in 1923.
A small amount of information from the library website and the street is probably named after Sulby in the Isle of Man.
Another street that I walked in August 2020 and there are some lovely houses here. The oldest house was built in 1905 and there are three from 1920s. Gradually the various large properties were subdivided with several houses built in 1990s. The Bates family that lived at 1 Sulby Rd were frequently mentioned in Papers Past.
