I know this is an old thread but it probably makes up part of Pontshonnorton Road now. Which was several streets (one of which was Norton Bridge Road), part of it was Police Row in the 1891 census, Police Row Norton Bridge Road, in the 1901 and Pontshonnorton Road in 1911.
Near Brookfield Lane (which is opposite the Royal Oak just near where Pontshonnorton Road starts) there is a house called Sunny Bank
Alternatively there is a Coronation Terrace next to the Oak which apparently used to have a different name
