Looked in 1911 census records there are only 6 houses listed for this street: No1 Robinson family, No2 Redpath family, No3 Foster family, No 5 Lowrey family & no6 Gregory family. Looking in 1939 records No 19 was occupied by a Mrs Dorothy Robson (widow b 1893) & her son Robert Robson (widower b 1911 a labourer in a brickyard). Would appear that the street was extended sometime between these records perhaps searching local planning records may tell you when this happened.
