Mormon colonies in Mexico
The Mormon colonies in Mexico are towns near the Sierra Madre mountains settled by early Mormon pioneers. They were founded by members of The Church of Jesus Christ of Latter-day Saints, including Brigham Young, Jr., and Charles Sreeve Peterson, in the 19th century as part of a large colonizing effort instigated by Brigham Young, which dotted the map of western United States, southern Alberta, and northern Mexico with Mormon settlements.
The two surviving Mormon colonies in Mexico are Colonia Juárez and Colonia Dublan. Both colonies are located in the state of Chihuahua, in the general vicinity of the Casas Grandes archaeological area. The Colonia Juárez Chihuahua México Temple, built in 1999, is located in Colonia Juárez, and is currently the smallest temple the LDS Church operates. In addition to the locations in Chihuahua, other (now abandoned) colonies existed in Sonora.
Members of the Pratt-Romney family have roots in these colonies, including both Marion G. Romney and George W. Romney having been born there.
Other areas
Many Mormon settlements in the United States are in areas that at one time belonged to Mexico, but nearly all of these were already part of the United States at the time of settlement. The exception is Salt Lake City itself, which was settled in the spring of 1847 and became part of the U.S. in 1848.
Book
Mormon Colonies in Mexico is also the title of a book by Thomas Cottam Romney. The book details the story of Mormons who sought refuge in Mexico after fleeing from US authorities for polygamy. The book is published by the University of Utah Press.
