Phyllis Gregory was the first wife of Naval Officer Bill Gregory, the on-off lover of Elsie Tanner. In 1962, Phyllis was separated from Bill and went to see him in Weatherfield to beg for a reconciliation. Bill felt guilty and agreed to return to Scotland with her, but decided not to tell Phyllis about his relationship with Elsie.
In 1970, Bill returned to Weatherfield to see Elsie and told her that Phyllis had died and they had split for two years before. It is unknown how or where she died.
