Church of the Firstborn (LeBaron family)
grouping of competing factions of a Mormon fundamentalist religious lineage
The Church of the Firstborn (or the "LeBarón family") is a grouping of competing factions of a Mormon fundamentalist polygamous family community that had settled in Chihuahua, Mexico, by Alma Dayer LeBaron Sr. by 1924.
Factions accepting leadership succession by some of Alma Dayer LeBaron Sr.'s sons self-describe as members of the Church of the Firstborn, without a legally formalized organization. What became over time the most substantial faction is that of Church of the Firstborn of the Fulness of Times, often shortened as the Church of the Firstborn, which was founded in September 1955 by three of Alma's sons, Joel, R. Wesley, and Floren LeBaron.
Since its founding, the order's most notable enclave has been within the jurisdiction of Galeana Municipality, Chihuahua. The LeBarons christened the LeBaron ranch Colonia LeBarón in the 1950s. Especially in more recent years, it is a minor segment of the order that engages in the practice of polygamy.
A substantial fraction of residents residing on and nearby order members' landholdings at Colonia LeBarón are not affiliated with the order, many of them identifying themselves on census reports as Roman Catholic and most of the remainder as evangélico (Protestant). A community that has inter-married but separate beliefs to Colonia LeBarón's is a three-hour drive away in rancho La Mora, 150 full-time residents strong, in Sonora.
Establishment
The LeBaron family, led by Alma Dayer LeBaron Sr., affiliated with the leadership of Mormon fundamentalist leader Joseph White Musser beginning in 1936.
