Lucy Barlow (née Richards) was a florist who Peter Barlow met while buying a bouquet for Shelley Unwin. Instantly attracted to her, an affair began. Lucy, unknown to Peter, hired Tracy Barlow at the flower shop, revealing later to Tracy that she was pregnant. When an unaware Tracy informed Peter that her employer was pregnant, Peter realised that the child was his. Peter married Lucy while he was engaged to Shelley, but promised Lucy that it was over with the Rovers landlady; however, Lucy kicked him out when she found out the truth. Her son, Simon, was born in early July 2003, but at first Lucy didn't want Peter to be involved with him. The final showdown came in the Rovers with Shelley meeting Lucy, who went on to show her wedding photographs.
