According to tradition of the historic church St. Mary-le-Bow, the city dweller must be born within earshot of what?
St Mary-le-Bow:  According to tradition a true Cockney must be born within earshot of the sound of Bow Bells (which refers to this church's bells rather than St Mary and Holy Trinity, Bow Road, in Bow, an outlying village until the 19th century). Cockney:  Originally a pejorative term applied to all city-dwellers, it was eventually restricted to Londoners and particularly to "Bow-bell Cockneys": those born within earshot of Bow Bells, the bells of St Mary-le-Bow in the Cheapside district of the City of London.
