Just like her husband, Joanna Parker's past is unknown. All that is known is that she moved to Sunset Valley to begin a family and to fulfill her wish. And in order to make that easier, Joanna became a housewife and later a stay-at-home mother to raise her five kids who all grew up, moved out and starting families of their own.
Currently, Joanna resides in Bridgeport living with Jordan and Jenna to support in their quest of fulfilling their lifetime wish.
Before the memory system was introduced, Joanna moved to Sunset Valley to be a stay-at-home mother and after a few days, she gave birth to twins, Jacob and Jared. And as a birthday present she adopted Lucky from their neighbor, the Clavells. After the Twins aged up, Joanna along with James partnered to teach them potty training and talking and they learned them almost back to back. Jared learned to walk before WooHooing with James and Jacob learned after. The next day Joanna got pregnant with Julia. She also taught Lucky how to hunt. Joanna threw a birthday party for Jared and Jacob where she entertained the guests by playing guitar. After their birthday party, she had Julia. Joanna gained fame by befriending Nick Alto who was a one star celebrity. When Julia aged up, Joanna taught her to talk right away. The next day, she WooHooed with James. She also adopted Pepper to have a cat in the family and potty trained Julia by the end of the day. The next day, Joanna got pregnant with Jordan, rode in a limo to the park. A couple days passed and it was birth days, birthdays and fires. Joanna went into labor while James was cooking so it started a fire. By the end of the day, Jacob and Jared aged up into teens. The day after, Joanna had aged up herself.
Two days later, Joanna saw Julia grow up into a child and Jordan into a toddler. Jordan learned to walk and potty trained back to back by her before learning to talk a few days later. She attended Thornton Wolff's party with James where she played guitar. When Julia turned into a teen and Jordan turned into a child, Joanna WooHooed with James one final time. They went on a date later that day before Joanna got pregnant early the day after. Three days later, she had Jenna, a day before Jared and Jacob aged up into Young Adults. Within the next few days, Karissa moved in, Jenna grew up, Jordan grew up, Joanna potty trained Jenna and taught her to talk. Joanna also saw Nick Alto die. On the same day Jenna learned to walk, she became a child, Joanna herself became an elder and Julia became a Young Adult.
A week later, Jenna became a teen and Joanna threw a Gift Giving Party. It was also the same day Joanna became a grandparent because of Julia. Sadly, at the party, Dorothy DeMayo died as well as Lucky with whom, she became BFFs with. Jordan also aged up the same day. Joanna picked up her grandson, Jack, before he moved to Appaloosa Plains with his parents. She caught a chipmunk and named it Chippy before moving to Bridgeport so Jordan and Jenna can fulfill their dreams. On the third day in Bridgeport, she visited a lounge with James where he died of old age, leaving her heartbroken and in mourning. Joanna died herself a week later of old age as well.
