Hope
Born in 1974(really, although she turned 18 about 10 years later), she was named Hope because her mother Addie had cancer while she was pregnant.  When Hope was just a baby, Addie was killed by a car when she pushed Hoope's carriage out of its path.  She was raised by her father, Doug Williams, and her half-sister, who later married Doug. 
Hope attended bording school, and returned to Salem in 1984.  There she met Bo Brady, and they realized that they had played together as children.  They fell in love, and later that year, after threats on Bo's life, she married Larry Welch(this marriage didn't last long). Bo and Hope were married in 1985.  In 1987, their son Shawn-Douglas was born.  In 1990, Hope was presumed dead in an explosion.  For four years, Hope was brainwashed to be Gina, and worked for Stefano DiMera.  She was found at Maison Blanche in '94, with amnesia.  She regained her memory, and she was thought to be dead again in an avalanche a few years later, but Bo eventually rescued her. 
Unfortunately, Stefano decided that he needed Gina back, and transformed Hope for the second time.  Now she is Hope again, and reunited with Bo.  And she became pregnant as a result of her actions as Gina, but it is Bo's child.  After a devastating baby switch that had her raising JT, someone else's child, and then being forced to give him up, Zach, the child she gave birth to, was returned to her. 
Recently, while searching for her cousin Jennifer Hope's plane crashed and she was presumed dead.  But this has happened to many times before, and this time Bo knows not to give up until he brings her back home.  Hope is now on the Captive Island with the other recent "dead" of Salem.
Hope has worked as a police officer, private investigator, and a model.
