Ivy Joan Tilsley (originally credited as Ivy Tyldesley, also Nelson and later Brennan) is a fictional character from the British soap opera Coronation Street. Played by Lynne Perrie, Ivy first appeared on-screen on 14 June 1971, initially on a recurring basis, before becoming a regular in 1979. As the character continued development, Ivy's stringent religious beliefs would become a synonymous part of her storylines on the show. Before becoming a regular character, much of Ivy's backstory is inconsistent; in her early appearances her husband was referred to as "Arthur", "Wilf" (with the surname "Tyldesley") and "Jack" (Bert Gaunt), who went on to appear in the show in 1975, after Ivy had stated she and Jack were childless. By the time she became a street resident and a more regular character, her husband was named "Bert" (Peter Dudley) and they had an adult son, Brian (Christopher Quinten). Ivy is the grandmother of Nick Tilsley (Warren Jackson) and Sarah Platt (Lynsay and Leah King). Storylines have included her quarrel with Brian's wife Gail (Helen Worth), losing her husband and son; and forming a relationship with fellow resident Don Brennan (Geoffrey Hinsliff).
