I think Atarah is right on this HOWEVER my O.S. A-Z Lancashire Atlas shows it as STREET, though the postcode finder of Royal Mail calls it Ave. Why Cromwell though? The name was given by Rev Charles Whitaker (hence Whitaker St) who owned the land but as Cromwell was anti-CofE, it is an unusual choice. It might be linked to Marshall St, also on Whitaker land, which was on the opposite side of Whalley Rd, and Whitaker might have admired Cromwell for marshalling the troops, but this is pure conjecture. He did like to link names - Orange, Lemon and Lime, Pilot and Port were his favoured names, though not all got used. There have been other examples, such as Cobham, of streets becoming roads or avenues. The best example of snobbery is that Mary-Ann St became Milton St.
