Yvonne Casey is the mother of Claire Casey. By her own admission not close to Claire as a child, she nevertheless provided support to her daughter during marital crises with husband Ashley, including babysitting Claire's young children Freddie and Joshua.
In September 2006, Claire began leaving home every day, telling Ashley that Yvonne had terminal cancer and needed her care. Claire was actually suffering from post-natal depression, but it was only after several weeks that Yvonne showed up at the Elliott & Son butcher's shop and told Ashley she'd been away learning yoga techniques, exposing Claire's lies. Yvonne and Ashley worked together to help Claire recover from her mental illness.
In 2007, Yvonne was on hand to help Claire again when she moved in with her, following the arson attack (started by Casey Carswell) which badly damaged the Peacocks' house. She objected to Claire's friendship with Casey even before the identity of the attacker came to light. Claire eventually returned home.
Yvonne turned up again in October 2010 outlining her plans to move to France, asking Claire and Ashley if they wanted to set up in business with her and her partner. Ashley was well against the idea, even faking an angina attack to put off the move. Although he later came around to the idea, he was killed in the tram crash before the move took place, leaving Claire a widower. However, the family's move to France still took place; after Tracy Barlow taunted Claire regarding Ashley's death, she assaulted and nearly killed her in a rage. The Peacocks absconded later that month, to avoid police action and presumably live with Yvonne.
