Kathleen "Kathy" Mershon Martin is the daughter of Tad Martin and Dixie Cooney. She was named after her adoptive great-grandmother, Kate Martin. Kathy has an older maternal half-brother JR Chandler, two older paternal half-brothers Damon Miller and Jamie Martin, and a younger paternal half-sister Jenny Martin. She was born on June 2, 2002. Kathy was given up for adoption by Dixie when she thought she was dying. Dixie lived and then spent the next four years looking for her, letting everyone think that she died. Kathy was adopted by Jim and Linda Mershon, and had a happy life. Jim and Linda later died in a car crash Christmas 2006, and Kathy was taken in by Julia Santos. Kathy lived with Julia for over a year, and went to live with her father Tad following Julia's death in May 2008. Kathy ran away from her father after hearing him and Krystal fighting about Krystal's affair. Kathy returned to her father and recently, Krystal returned to her family and is currently living with her daughter and ex-husband. In August 2011, it is revealed that her mother Dixie is still alive, and they meet for the first time.
