Lowther Street in Sockburn and there wasn’t any information on the library website for this street. Searched Papers Past and there was only three entries and two involved name change of the street. In 1969 Racecourse Rd deviation was renamed Lowther St and in 1971 there was an accident on the street. I searched Ancestry website and no one with that surname lived in this area. The most likely reason for the name is horse racing related as there is a race in Great Britain called Lowther Stakes.
I actually walked this street by accident as I thought that I was still on Racecourse Rd. It is confusing as Racecourse Rd becomes Lowther St without any break in the road whereas you have to turn a corner to continue on Racecourse Rd. Only businesses here and most are car sales.
