Cassidy "Cassie" Newman (adopted; gave up custody to birth mother, Sharon Newman; deceased)
Sixteen-year-old Sharon Collins and her single, paraplegic mother, Doris, lived in Madison, Wisconsin, after being abandoned by Sharon's father. Sharon's best friend in high school was Grace Turner. When Sharon told her high school boyfriend, Frank Barritt, that she was pregnant after he had pressured her to have sex, he wanted nothing to do with her or his child. Sharon and her mother decided to give the baby up for adoption because they felt they were unable to raise her properly. The baby girl was adopted by Alice Johnson and named Cassidy. Alice later abandoned Cassie to pursue a man and left the child in the care of her elderly mother, Millie. Cassie loved Millie, but it was very difficult for a woman of Millie's age to keep up with a young child, and Cassie had no friends but her dolls, and nowhere to play but in the dirt.
Sharon ended up marrying Nick Newman, son of wealthy industrialist Victor Newman. When it appeared that Sharon and Nick's newborn baby Noah was going to die, Sharon's best friend Grace Turner and her boyfriend Tony Viscardi tracked down Cassie to help Sharon ease the pain of her loss. They convinced Millie to allow them to take Cassie, who was five years old, to Genoa City to be united with her natural mother. But Noah lived, so Grace decided to keep Cassie until the "time was right" to tell Sharon. Grace fell in love with the engaging child and kept her true identity to herself for over a year.
After Grace finally told Sharon who Cassie really was, Cassie went to live with Sharon, Nick, and Noah. Alice Johnson later reappeared and hired a lawyer, Michael Baldwin, to fight for the return of "her daughter." Although Alice was about to win custody, Sharon and Nick were able to convince the jobless and flighty Alice that Cassie would be better off with them. Alice gave up her parental rights, and Sharon was awarded custody. After a waiting period, Cassie legally became a Newman when Nick adopted her, and she lived with her happy family in a converted barn on the Newman ranch. Cassie was tragically killed in an auto accident when she was 14 years old. The memorial service was touching, with Grace, Millie, and Alice conspicuously absent.
A few months after Cassie's death, a still grieving Nick went to see Alice to talk to her about Cassie. He needed her to tell him some things about Cassie that he had never heard before. Alice told him about a time that her perfume bottle had been broken and how Alice's mother, Millie, had tried to cover it up by taking the blame. However, Cassie had always had to be honest and made sure that Alice knew that she had been the one who had really broken it. Nick was happy to hear the story. He thanked Alice and returned home.
