Kelly-Marie Maguire (née Ball) is the sister of Kevin Ball and the ex-wife of Shane Maguire. A former heroin addict, she occasionally visited the Chatsworth Estate to see her brother when she had nowhere else to go. However, her return in 2007 was permanent. She became a prostitute and began working at Lillian's brothel, becoming a superior role in the business. She gained status on the estate by marrying Shane Maguire. But the marriage ended when she fell in love with Marty Fisher. She eventually left the estate in 2013 after cutting her ties with her friends and family.
