Mark, 48, lives in South Central Kentucky with his wives, Marian, 32, and Heidi, 23. Together they are raising seven children under the principle of Celestial Plural Marriage, also known as polygamy. Their beliefs about plural marriage are rooted in their faith, what they call independent fundamental Mormonism. Mark leads the family in a home church service each Sunday. Marian and Heidi home school the children. The family lives a life of sustainability, growing their own fruits and vegetables, and using solar energy to power their home.
