Josslyn is the daughter of Carly Jacks and Jasper “Jax” Jacks. Sonny is her step-father. Despite having a chaotic upbringing, Josslyn is very strong-willed and smart. She has a strong sense of right and wrong, and she isn’t loathe to share her opinions. When she was young, she hung around with Spencer Cassadine and had a crush on him. She also hung out with Cam, who became her boyfriend later on.
Josslyn’s first boyfriend was Oscar, who died of cancer. She became involved with Cam after him. She and Cam made love, but Esme filmed them and streamed in online, so that was traumatic for both teens. It was the beginning of their breakup.
Josslyn had cancer as a baby and had to get a kidney transplant. Nelle Benson’s father sold her kidney to Jax. (Nelle later came to down and wanted revenge)
Her next boyfriend was Dex, who does security for Sonny (but is secretly working for Michael, her brother).
Josslyn has a large extended family, which includes her late brother, Morgan. She was also very close to Jason Morgan. She’s had to endure a lot of loss in her young life, but she is very resilient. She can handle just about anything.
