Ivy Joan Brennan (née Nelson; previously Tilsley) was a Coronation Street resident from 1979 to 1994, wife of Bert Tilsley and later Don Brennan, mother of Brian Tilsley and grandmother of Nick Tilsley and Sarah Platt. Prior to living in the Street, Ivy had worked at the Mark Brittain Warehouse and factory Baldwin's Casuals, where she served as shop steward and supervisor. She was never afraid to speak her mind and was used to standing up to the management on behalf of her fellow machinists, including Ida Clough and her closest friend, Vera Duckworth.
