Andrea is the third of 12 children to Daniel Kingston and his sixth wife, Heidi Mattingly Foster, who today still belong to the polygamist group known as the Order. With the help of her aunt, who called the police and filed a protective order against Daniel for both Andrea and her sister Jessica, she managed to break free from polygamy at the young age of 12. During a nationally covered custody battle, Andrea was placed in foster care, separated from Jessica. Eventually, their parents were ruled unfit to raise Andrea and Jessica and they relinquished parental rights. Andrea and Jessica have remained close and have spent the past few years helping others escape the horrible life they once knew. Today, Andrea is in law school pursuing a career in public service law.
