Sister Wives patriarch Kody Brown gets a lot of blame for destroying three of his marriages, but Robyn Brown is the one who’s sabotaging their marriage. Robyn is Kody’s fourth and final wife since his three other wives divorced him throughout the last few years. Robyn and her three children from her first marriage joined the Brown family in 2010 during season 1. At the time, Kody was already married to his first three wives, and the large family all lived under one roof in a massive house in Utah. The home was designed by a polygamist and meant for a polygamous family, so each wife had her own wing with her separate kitchen, and Kody would go from wing to wing.
