Benjamin "Ben" Brown is a nephew of Kody Brown's. He's known on TikTok as @thefreshkingbenjamin.
He did an episode of Year of Polygamy here.
He grew up in a family with three moms: two who married his dad at the same time (one being his mom) and then a third wife who was only around for a couple years. They had 16 kids. Ben was his father's 3rd and mother's 1st.
