Wash Brow is off Tottington Road on the left, in Bury, in the Woolfold area. I am looking at an A to Z from the late 60s. It is between Wash Fold and Wash Terrace, before Scobell St.
There has been much redevelopment in the area just above Bury Bridge where roads go off to Bolton, Walshaw, Tottington, Brandlesholme for Holcombe Brook and Ramsbottom, and Walmersley.
Have you any census details?
