• Controversy surrounding her church

The Marriage Controversy

Mary married her step-grandfather, Robert Cosby Sr., after her grandmother passed away. She has said it was her grandmother’s wish for her to inherit the church and marry him, which sparked major public discussion and became a central storyline on RHOSLC.
