Abigail Johanna Devereaux is the only daughter to Jack and Jennifer Devereaux. She was named after Alice Horton's mother, Abigail and Jack's mother, Josephine. Abby was brought up very well by her parents and is a good, sweet girl.

After Abby's birth, she came down with aplastic anemia as a result of drinking polluted well water. When Jack discovered that he was responsible, he left town. Abby developed leukemia but a bone marrow donation from Austin Reed saved her life. Jen had been dating Peter Blake at this point, and Abby started to associate him with her father. When Jack came back, Abby and her mom moved to Africa for a few years. They lived in Ireland for a while as well and moved back to Salem after finding Bo Brady there (her honorary 'Uncle'). Jack soon followed and Abby hoped that the two would get back together. After relationships with Brandon Walker and Colin Murphy, Jen and Jack found their way back to each other and married. Abby was devastated when she heard her father had been murdered by the Salem Stalker (Marlena). Jen had to take Jack off life support and Abby blamed her for this, turning to her grandfather Vern for comfort. She was happy to find she was to have a little baby brother when Jen found she was pregnant and started to come around when new friend and boarder Patrick Lockhart made his appearance in Salem.

Abby was sent away when her mother went on the search for Jack, who was alive again but presumed dead. Jen and Abby saw many rough times before Jack came back to them. She had a new baby brother, Jack jr., and a new friend in Chelsea Benson Brady. Chelsea turned out to be a bad influence on Abby and she went through more rough times.

Eventually, Jack was found to be alive and the family was reunited. Jack became ill shortly after his return and almost died, before a miracle drug saved him. After, Jack and Jen moved to England with the baby and Abby stayed behind with Aunt Maggie. She lived with her aunt and cousin/friend Nick Fallon, and was in love with Max Brady.

Abby was set to leave for Europe to visit her parents one summer. She wound up going to boarding school while away but returned in March to Salem, to stay. She met Chad by chance at Java, who was with Johnny, and assumed the boy was his son. She didn't take kindly to 'boys getting high school girls pregnant' so they got off on the wrong foot. Once she apologized, they seemed to get along until he revealed he's a DiMera and then she judged him again. She got to know him a little and apologized for pre-judging. She and Chad became friendly since, though he disliked how she kept judging his family.

She was having issues as a cause of missing her brother JJ and worrying about her mother and father's divorce. Abby became a hospital intern and was interested in Chad, but had issues accepting that he was a DiMera. Abigail finally accepted Chad for who he was and they created a loving relationship.

Jack returned from Afghanistan, and she learned he was held hostage for a very long time. She was hurt and angered that he left them to follow a story, but after a while she seemed to forge a decent relationship with her father. When Chad accidentally kissed Melanie at the Halloween dance October 2011, thinking Mel was Abby, Abby became upset. Things seemed to go downhill after that and when she was reacquainted with Austin Reed she became attracted to him. She couldn't stop thinking about him, though he only saw her as a friend. She and Chad broke up, after realizing that they didn't belong together, and Abigail learned he and Melanie were into each other. Abby was hurt and felt betrayed.

Abby leaned on Austin for support and later became his teaching assistant. She fell for him and became obsessed. One night he got drunk and she pretended they had sex. He was beside himself for "cheating" on Carrie, but eventually it was learned that nothing happened. Abigail admitted she was lying. She was ashamed of herself but ultimately got back on the horse and started dating Dr. Cameron Davis. Things went slowly and one night he took her to her room for sex and she backed down. They broke up and she divulged to her mother and Gabi that she was a virgin. She didn't want Cameron to know. They eventually started dating again and she was at the point where he could figure out her "secret." Cameron eventually did find out and didn't care.

Abby thought Cameron would be the one she'd lose her virginity to but Chad DiMera returned to her life and made it known he was into her. She was torn between the two guys and eventually Chad faked a brain tumor with Cameron who then decided to let Abigail go. She and Chad dated exclusively and made love right away, and all the while, he kept the fake tumor from Abigail. During a speech he was making at Sami and EJ's engagement party, Marge Bernardi shot him. EJ was forced to tell Cameron the truth about there being no tumor in order to save Chad's life. Cameron urged Chad to tell Abigail the truth, and when he finally did Abigail ended things with him and he left Salem to get treatment for a newly-found heart condition. She confronted Cameron in his part in covering up the lie, and he left Salem shortly after too.

Abigail began to wonder why she had not heard from her cousin Nick since he left for New York. She began doing some digging and when she got close to realizing something had happened between him and Gabi, EJ DiMera – in order to protect Sami - was tasked with getting Abigail off track. EJ found her at the Horton cabin one night and the two got into an argument. Their heat quickly turned to passion and they slept together. They both thought it would just be that one time, but their chemistry was undeniable and Abigail kept sleeping with EJ – including in a hospital supply closet and a gym locker room shower. After a pregnancy scare Abigail began to believe EJ was only with her because Sami was withholding sex. He admitted he loved Sami and the affair was over.

Abigail began a flirtation with new-in-town bartender Ben Rogers. When Ben saw Abigail and Nick arguing, he defended her. And when Nick later turned up dead, Ben was there for Abigail too. They began dating and soon made love. At the same time, Sami was insistent that Abigail be her maid-of-honor when she wed EJ and so Abigail - reluctantly and full of guilt - threw herself into planning. Abigail was unaware that Sami knew all about her affair with EJ and was really plotting revenge on her. After the wedding Sami went to Abigail’s house to share pictures of the wedding with her and her mom Jennifer. What she really did was show them pictures of Abigail and EJ together at the cabin. Abigail was horrified as Sami made sure everyone knew about the affair. She had Abigail’s name inserted in Will’ Horton’s magazine expose about Sami and EJ naming Abigail as his mistress, then got her fired from her job at the hospital. Ben stood by Abigail through the whole thing and they moved forward as a couple. And when EJ was killed, he stood by her again.

Soon after EJ was killed Chad returned to town and immediately argued with Abigail, furious at her for sleeping with him, then his married brother. After he cooled off Chad promised Abigail that he only wanted the best for her, and even got her reinstated at the hospital. But he constantly butted heads with Ben and eventually filed charges against Ben for hitting him after he goaded him with an inappropriate comment comparing sex between Abigail and Ben’s sister Jordan Ridgeway. Chad offered to drop the charges if Abigail slept with him, but she refused. The charges were dropped anyway and Abigail was tapped to oversee the DiMera Foundation’s new project at the hospital, working with Chad.

Chad convinced Abigail that he really was her friend, which infuriated Ben. Ben asked Abigail to move in with him and while she thought about it he installed a tracker on her phone. Abigail loved Ben but kept spending time with Chad and one night, slept with him. She hated herself for cheating on Ben and after she learned that Stefano wanted her to marry Chad in order to get control of some family land of hers in Ireland, she agreed to move in with Ben.

Ben followed Abigail one night when she went to ask Chad to always keep their secret but never told her he found out about the affair. When Abigail realized she was pregnant shortly after she had no idea who the dad was. She had Kayla run a paternity test and the results showed Ben was the father. Abigail did not know Ben’s father had changed the results in order for his son to get the pricey land and Chad was really the father of her baby. She accepted Ben’s proposal and moved forward making a life with the bartender.

Chad told Abigail he still loved her but she was determined to marry Ben and raise her baby with his real father. Chad was sad but proved he only cared about her when he outed Stefano’s plan for her land in front of him.

Ben grew increasingly paranoid and jealous over Abby’s relationship with Chad and he made a plan to get them away from each other forever. Unbeknownst to Abigail he became a serial killer in order to implicate Chad in the crimes. And for a while, it worked. Chad was arrested for the killings, but Abigail couldn’t believe he was the murderer which only angered Ben more. Ben took Abigail out of town and held her hostage in a cabin. He chained her to a chair and held a gun on her, causing her to go into labor early. Ben got a midwife to help, then shot her and buried her.

Ben named Abigail’s baby Colin and decided they all needed to leave. He only agreed to bring Abigail so she could feed the baby, otherwise he was done with her. Chad arrived to save Abby and Ben locked them up in the cabin together. He lit it on fire and left with the baby. Abigail was hysterical but it wasn’t long before baby and mom were reunited, and Ben was sent to a mental hospital.

Abigail and Chad’s relationship progressed quickly after the baby was born, but hit a snag when Chad’s brother Andre brainwashed him to despise Abigail and go after Belle Brady for some money her sister Sami had embezzled from the family. But through her love – and the revelations that Chad was actually the baby’s father - they were back on track. They renamed the baby Thomas Jack and began to plan their wedding.

After his father went missing and presumably left the country, Chad insisted he and Abigail move into the mansion. She was not happy about it but agreed for Chad’s sake. He mother did not approve of her decision, and neither did her brother, but Abby was insistent she was doing what she wanted for her family. Meanwhile, Abigail was beginning to worry about her mother’s pain pill popping, but Jennifer insisted she was fine.

As the date drew near for Abigail’s wedding to Chad, news broke that Ben had escaped. Knowing he still thought the baby was his Abigail began to panic that he would come after them. She began to see visions of Ben but went through with her wedding to Chad on March 15, 2016. Still, she was convinced he was stalking them and when her nightgown was shredded she was surer than ever. She, JJ and Chad decided to make a plan to lure Ben to them as Abigail began to worry she was going crazy and making it all up in her mind. Even when she saw him in front of her and he touched her cheek, she questioned her sanity. Eventually, Ben really did show up and with Chad incommunicado, Abigail set up a scene to lure Ben into bed and then knocked him out, tied him up and set fire to him. Chad arrived just in time and Ben was sent away. This sent Abigail over the edge and she was committed to Shady Hills psych ward to be cared for by Dr. Robinson. Soon, Abigail wasn't getting better and kept seeing Ben. She finally set fire to the ward and took off. Andre gave Chad a goodbye letter from Abigail and then faked her death, saying she was aboard a flight when it crashed into the ocean. She finally revealed herself months later. She had been taken care of by her grandmother, Laura and Andre DiMera for PSTD. She revealed herself to Chad after Jennifer and it took time but they were able to forge a relationship again, though by then, Chad had also fallen in love with Gabi Hernandez. Chad took a while to get over his feelings for Gabi. It was awkward and painful for all involved. Abigail started to think Gabi belonged with Chad, which confused everything. Eventually, Chad said he wasn't in love with Gabi, he only had eyes for Abby. By then, Abby had moved on to help Dario Hernandez who told her he needed to get married to someone in order to stay in USA and not be deported to Mexico. She and Dario married. She learned Dario was lying and tried to leave him but he threatened Chad, saying he thought Chad killed Deimos. He showed Abby a photo of Chad standing over the body but Abby had Theo delete it, then she left Dario. He took off and she got back together with Chad. They married October 4, 2017 but not before Ben Weston interrupted their vows to tell them all that Will was alive. Abigail punched Ben in the face and he was taken back to Bayview Sanitarium. Abigail and Chad enjoyed married life until Stefan O DiMera arrived to town, the son of Vivian Alamain and Stefano DiMera. Stefan was interested in Abby and she detested him. Abigail started displaying symptoms of DID. It turns out she had two personalities in Gabby (Gabigail) and Dr. Laura. Gabigail is a vixen who kissed Stefan, while Dr. Laura's the protector. When somebody killed Andre DiMera, Gabi Hernandez was a suspect but it turned out that the women in the security video footage the police saw entering and leaving his office looked like Gabi but was Abigail or Gabigail. Stefan soon realized Abigail had DID and two alts, Gabby and Dr. Laura. He was intent on hiding it from everyone and set up Gabi for Andre's murder in order to take the heat off Abby's alt.
