By the time Dolly and husband Samuel moved to Coronation Street, they already had four children - George, Thomas, Flo and Betsy. Dolly grew up alongside Sam as they lived next door to each other on the same tenement block on Barkers Lane. At fifteen, she was married and pregnant with her first child.
