Cheryl Crowther was Jack Tilsley's fancy piece. In April 1972, Jack's wife Ivy caught Jack and Cheryl together at the Tilsley household and walked out on her husband. After a week or so, the couple reconciled.
- When the character of Ivy Tilsley became more prominent in the late 1970s, a new backstory was created for her and her husband Jack Tilsley was written out of ongoing Coronation Street history. This Wiki makes no attempt to reconcile Ivy's backstories, and treats all parts of Street history as equally "true".
