Mariah Maximilliana Jones is born on Halloween night in 1990 and named after her maternal great-grandparents Maximilian and Mariah Ramirez. Her Godparents are named as Sean Donely (John Reilly) and Anna Devane (Finola Hughes) at her Christening. In 1994, she suffers from Kawasaki disease and requires a heart transplant. Meanwhile, her cousin B.J. Jones (Brighton Hertford) is in a car accident, leaving her brain dead. Test results prove B.J.'s heart to be a match for Maxie. B.J.'s parents, Bobbie (Jacklyn Zeman) and Tony Jones (Brad Maule), agree to take B.J. off life support and donate her heart to Maxie. During this time, Maxie's sister Georgie is conceived, but their father Frisco Jones (Jack Wagner) leaves town again soon after.
