George Greenwood was the husband of Nancy Greenwood and father of Liz.
Liz married army sergeant Jim McDonald in 1974, by which time she was already pregnant with twins Andy and Steve. The family lived in army housing but with Jim abroad for long periods, Liz raised the boys virtually on her own. Fifteen years later Jim was demobbed and one of the couple's reasons for moving to Coronation Street in 1989 was to be close to George and Nancy.
In 1990, Liz told Sally Webster that George used to keep pigeons when she was a child. George had died sometime prior as in July of the same year, Liz had asked Steve to drop £10 off to his grandmother. In January 1996 however, Nancy had left Weatherfield and settled into a new flat in Southport.
