Sowerby Place – nothing on library website about this street. It sounds like someone’s surname. Only a couple of houses at this stage but others were being built.
With further research found this information – Sowerby Place – It is a village in Yorkshire where the Greenwood family have lived for hundreds of years. Additionally, Austin Mitchell, the MP for Great Grimsby and who is well known to New Zealanders, has a summer home in Sowerby. Interestingly, the village also appears in the Doomsday book of 1086. Found this on-line from the minutes of the Hagley Ferrymead Community Board meeting dated 16/03/16
The Greenwood family are more likely to have lived at Sowerby Bridge and not Sowerby but haven’t had time to check Ancestry website.
