Soapcentral didn't have Rex's bio, but did have one for Gina:
Gina's parents were "con artists" when she was growing up, and all did time for their crimes. Brother Danny, not wanting to be a part of it, ran away from home as a teenager and ended up in Genoa City working as a waiter at Jonas's Restaurant with Paul Williams. Gina, (with shortened last name Roma), came to Genoa City after getting out of prison, wanting Danny's help to "go straight." For a long time Danny didn't trust her, but got her a job singing at Jonas's. Danny began his career as a teenage rock star doing concerts in Genoa City. He was often joined by sister Gina, and friends Tracy Abbott, Lauren Fenmore, and Amy Lewis, who sang with him when he performed on stage. When Jonas decided to move on, Gina bought the restaurant and renamed it Gina's Italian Restaurant.
Lauren Fenmore's divorced father Neil, began to show an interest in Gina. They dated and fell in love. But Lauren's long lost mother Joanna Manning returned to GC, and Lauren wanted them back together. So she broke up Gina and Neil by exposing that Gina was an ex-con. Gina vowed to get even with Lauren.
In 1987, Danny and Gina's father turned up in Genoa City, a homeless drifter just out of prison. He was molded and renamed by Jill Foster Abbott as "Rex Sterling" to con Kay Chancellor. But Rex and Kay fell in love, and he became a "good guy" after all. (Danny, Gina and Rex ended up becoming very close until Rex's untimely death by gunshot years later, as he surprised Esther's boyfriend Norman burglarizing their safe.)
In 1989, Rex's former cellmate, Clint Radison, showed up in town. Clint discovered Gina was Rex's daughter and started wooing her, and got her to marry him. But Clint was working on a new scam. He found a woman named Marge who worked at a diner that was a dead ringer for Kay. Clint and his cohorts trained Marge to pass for Kay, then held captive Kay and her "ditsy" maid Esther. Meanwhile Marge posing as Kay drove Rex away, and he filed for divorce. Clint was now free to liquidate Kay's assets. But Brock made a surprise return from his missions in India. Brock, with the help of Mitchell Sherman, discovered the ruse, and rescued Kay and Esther. Clint was sentenced to prison, and Gina turned to Brock. They became very close, but Brock was off on another of his missions to save the world before long.
That same year, Danny was attacked by a mugger and received major kidney damage. He needed a transplant to survive. Gina, Paul, Phyllis and Christine were all ruled out as possible donors, and things were looking bleak. In a last ditch effort to prove to Christine that he was a changed man and worthy of being reinstated as a lawyer after his prison term had been served, Michael Baldwin came to the rescue and donated the needed kidney. After Danny's recovery, Chris made her decision between Danny and Paul, and chose Paul. Danny took Daniel, and went "on the road." Only Gina kept in contact with him, receiving photos of Daniel now and then which she refused to share with Phyllis, whom she still considers the devil!
Gina continued to own and run Gina's for many years, Genoa City's gathering spot, renowned for it's excellent Italian food, entertainment and dance floor. She was always there to greet and seat the guests, sing a song now and then, listen to customer's woes or pass on a message, give a newcomer a room upstairs, give a new singer a break, and conveniently overhear conversations which kept her in the know of all of Genoa City's residents. She is a good friend to most of them, especially Katherine Chancellor, which whom she holds opens her restaurant each Thanksgiving with free food for the homeless. Singers to grace the Gina's stage have included Danny, Lauren Femore, Callie Rogers, Ryan McNeil, and John Abbott. John joins Gina in song now and then, and is frequently seen at the Abbot mansion for family get-togethers and on John's arm at Genoa City events.
While attending the 2003 Arts Council Gala with John, Gina received a call that her restaurant was on fire. They rushed to the scene and witnessed the place fully engulfed in flames by arson. John took the distraught Gina home to the Abbot mansion before it was even extinguished and she is living there still. Gina lost not only her restaurant, she lost her home which was upstairs and everything she had, but her whole life - which indeed the restaurant was. Gina's had a long history on Y&R. Originally named Pierre's, it was owned by Pierre Roulland who entertained his customers by singing. After Pierre's murder during a robbery of the restaurant, it was sold by his widow Sally to Leslie Brooks, and became the elegant Allegro. A retired concert pianist, Leslie entertained playing a baby grand. After Leslie moved on, it was sold to Jonas (who never used his last name) and became more of a dark bistro.
Gina's brother Danny returned to Genoa City lend moral support to help Gina get her life back together. The Athletic Club offered Gina the manager position of their elegant restaurant, and she accepted. She has apparently decided against spending the insurance money to rebuild Gina's Restaurant. She recently lost her occasional boyfriend John Abbott to the wily gold digger Gloria Fisher. Brother Danny has gone back on tour, leaving Daniel Jr. with his mother Phyllis.
****I don't remember Michael giving Danny a kidney!
