Kody Brown and the Sister Wives family are generally identified with the Apostolic United Brethren (AUB) , a fundamentalist Mormon sect that practices polygamy.

Quick scoop

The AUB is the group most commonly linked to the Browns in reporting about the show. It’s an offshoot of Mormon fundamentalism, not the mainstream LDS Church, and it continues plural marriage as part of its beliefs.

Why this matters

  • The LDS Church officially banned polygamy in 1890.
  • The AUB and similar fundamentalist groups still practice it.
  • Early coverage of Sister Wives described the Browns as fundamentalist Mormons in this tradition.

Bottom line

So the short answer is: they belong to the Apostolic United Brethren, or AUB.

TL;DR: The Browns are most commonly associated with the Apostolic United Brethren, a Mormon fundamentalist polygamist sect.[15][1]
