Age 22

Greene Family Farm, Georgia

Maggie grew up on her family farm in Georgia and was raised by her loving and religious parents, Hershel and Josephine Greene. On one occasion, Hershel and Josephine took her to visit the Amicalola Falls, the tallest waterfalls in Georgia.

Early in Maggie's life, her mother died. By the age of six, Hershel remarried a woman named Annette and gave birth to Maggie's half-sister, Beth along with Annette's son and Maggie's step brother, Shawn. Hershel's marriage to Annette caused distraught Maggie to smoke and shoplift in her teen years. After her father told her they should "love each other", Maggie grew to have a loving relationship with her step-mother and step-brother. Though her days of smoking and shoplifting were over, she used a tractor to crush her ex-boyfriend's Chevrolet Camaro when she was in high school.

By the time Maggie became an adult, she began to attend college. While there, she also got on birth control and became sexually active. On her first summer back home from college, Maggie left her bags in her room and went horseback riding, but when she returned she discovered that her younger sister Beth had been rummaging through her bags and found her birth control pills. Maggie was furious when Beth threw them into the pond out in horror. Although they began to argue, they eventually ended up reconciling because they were soaked in mud because of Maggie's horse, and Beth covered for Maggie when Hershel asked what had happened.

Maggie is Hershel's confident and athletic eldest daughter and the sister of Beth Greene. As the outbreak began, Hershel barricaded the Greene family and friends on the farm. It was during this time that her once-strong sense of faith began to dwindle, and she was left with doubts about what she believed in. She frequently made supply runs for everyone.
