2001-2012: Birth and early lifeEdit
Gabby was born into controversy, as no one had any idea whether Ashley or Bernice's former lover Carlos Diaz was her biological father. Tests soon proved Ashley's paternity. He and Bernice reconciled, but Bernice struggled with motherhood, a struggle which made her leave the village when Gabby was just a few months old.
Ashley lived as a single father for several years, until he began dating Laurel Potts, finally marrying her in 2005. Laurel became the primary maternal figure in Gabby's life, and Gabby also gained more additions to her family with the arrivals of grandfather Sandy Thomas and cousin Jasmine Thomas and in 2007, a half-brother, Daniel Thomas. Gabby's life was thrown into turmoil when Daniel died several months later, and Laurel and Ashley were torn apart over the news that Arthur Doland was actually their biological son, switched at birth. Gabby felt ignored, and began acting out after seeing her parents in constant conflict. After Arthur became a part of the family, things settled down.
When Sally Spode arrived, Gabby was always sent to her bedroom, so she could not see Laurel. At the end of Sally's scheming Gabby became upset. Laurel left and told Ashley that she wanted their children to join her for Christmas Day which Ashley agreed to, even though he was not invited. In 2010, Laurel's father Douglas Potts returned to Emmerdale and this made Gabby very happy as she and her Doug became very close. She enjoyed spending time with him and made him realize that she loved him, by giving him a painting she did at school, with Laurel, Ashley, Arthur, Sandy and herself in the picture.
2012-2015: Family troubleEdit
More turmoil hit the family in 2012 when Laurel broke up with Ashley due to his abuse of Sandy. She eventually began dating Marlon Dingle, while Ashley eventually became homeless. Gabby lashed out at Marlon. Further complicating matters was the return of Bernice after a decade away, now wanting to spend more time with Gabby. As a result, the family splintered between Laurel, Bernice, and eventually Ashley's new relationship with Harriet Finch.
Gabby became a vegetarian, although she confessed to Ashley that she did this partly to annoy Bernice.
In 2015, Gabby was traumatised when a drunken Laurel picked her up from school, calling her a "bitch," and later, erroneously telling her Ashley had died after a car accident. Bernice began dating, and later married, Lawrence White, delighting Gabby, who saw the perfect opportunity for lots of expensive presents.
