The beloved older child of super-couple Jack Harcourt Deveraux and Jennifer Rose Horton Deveraux, Abby has recently returned to Salem after spending time studying in England and Spain. Always the darling of her parents, the fresh-faced co-ed is still getting her bearings back home.
As a baby, Abby was named after Alice Horton's mother Abigail and Jack's mother Josephine. She was afflicted at a very early age with aplastic anemia, caused by her exposure to polluted well water. Her father Jack was so wracked with guilt at harming his daughter that he left town.
Eventually, Jack returned and convinced the entire Deveraux family to relocate to Africa for a few years. Abby's international upbringing also includes a stint in Ireland, where she and her mother lived before returning to Salem. When her itinerant dad also returned to town, Abby hoped against hope that her parents would reunite - but her mom could not be swayed. In a sad turn of events, Abby's father soon fell victim to the Salem Stalker. With the father of her children literally at death's door, Jennifer had to make the fateful and heart-wrenching choice to turn off his life support. The decision infuriated Abby and drove a wedge between mother and daughter. Miraculously, Jack wasn't really dead; to Abby's delight, her family soon reunited.
Before long, Abby and the family welcomed its newest member, baby Jack Jr. But the joy was short-lived: not long after the arrival of baby Jack, Jack Sr. became ill. As soon as he was able to recover, Abby and the family moved to London, where she began her college career. Eventually, Jack left his family once again, this time to find himself on a "walkabout." In actuality, Jack was kidnapped and held prisoner in Afghanistan.
Now a young woman, Abigail returned to Salem and definitely shook things up. She quickly captured the heart of Chad DiMera, and the two soon became Salem's young "it" couple. But as their romance started to wane, Chad started to stray, and he soon fell for her best friend, Melanie. When she learned about their affections for one another, Abigail was at first angry, but eventually accepting, realizing that her relationship with Chad was over. Additionally, the return of Abigail's father, Jack, put her in an emotionally trying position, but she eventually accepted him back into her life. Shortly thereafter, Abigail had an infatuation with the much older Austin Reed, almost ruining his relationship with Carrie.
Abby finally finds comfort with a man her age, falling for Cameron Davis when he arrives in Salem. But the gas explosion definitely shakes things up for Abigail; when Jack comes to her rescue while she's trapped in the elevator, the cable breaks and he plummets to his death, leaving Abigail wracked with guilt. Will Abby be able to bounce back from the devastation in the comfort of Cameron's arms?
