List of Mormon family organizations

Mormon family organizations (i.e., family organizations or associations) are entities created by members of the Church of Jesus Christ of Latter-day Saints (LDS Church) to accomplish the basic purposes of family life as understood within the church, in order to establish and strengthen family unity and identity across multiple generations.

Importance
As the basic unit of society, the family is also the fundamental organization within the LDS Church. LDS Church members tend to be very family-oriented, and have strong connections across generations and with extended family, often through regular family reunions. For LDS Church members a knowledge and appreciation of one's lineage and heritage is closely connected to the sacred ordinances conducted in LDS temples.

In its most general sense, the term "family organization" as used within the church refers to the fundamental concept of eternal family structure encompassed by the Plan of Salvation. More specifically, "family organization" refers to organizations created to provide structure and direction in meeting immediate and long-term family objectives and purposes. In connection therewith, LDS Church leaders have regularly taught the importance of establishing and supporting family organizations.

During the 20th century as part of the church's semi-annual General Conferences, a "Priesthood Genealogy Seminar" was conducted by LDS Church leaders in which the importance of family organizations was frequently emphasized. "[E]stablishing and maintaining family organizations for the immediate and extended family" has been expressly listed as an appropriate way to observe the importance of the Sabbath day in General Conference addresses and other church publications.

Purpose and organization
In 1978 the church asked all families to organize themselves at three levels: as "immediate" families, "grandparent," and "ancestral." Individual or immediate families are regularly encouraged to hold weekly Family Home Evening and participate in family councils. More formal family organizations consist of the descendants of a common ancestor. The purposes of such family organizations may include coordinating family efforts in promoting welfare, education, conducting family history research, holding reunions, compiling family newsletters and publications, and other family-related LDS practices. Commemorating family heritage and legacy is another typical purpose and activity for family organizations. In September 2016, LDS Ancestral Families Association (LDSAFA) was established as a "free registration, publication and support consortium for LDS Ancestral Family Organizations (AFOs)."

Influence
Formally constituted family organizations figure prominently among descendants of some Mormon pioneers and other early converts to the LDS Church. The longevity of and degree of organization found among many Mormon ancestral family organizations is noteworthy. For example, the Jared Pratt Family Organization was founded in 1881, making it one of the oldest family organizations in the United States in continuous existence.

In 1971 the Internal Revenue Service of the United States issued a Revenue Ruling determining that non-profit family organizations that are expressly "formed to compile genealogical research data on its family members in order to perform religious ordinances in accordance with the precepts of the religious denomination to which family members belong" are exempt under Section 501(c)(3).

Given their extensive documentation of lineages connecting many thousands of living individuals to a single common ancestor, their relatively larger extended family size (attributable in part to the early Mormon practice of plural marriage), relatively larger immediate family size, religious emphasis on "clean" or healthy living, and relative longevity, the genealogical data maintained by many Mormon ancestral family organizations have also been instrumental in medical research of genetic disorders. The University of Utah has made unique contributions to the study of genetics due in part to long-term genealogy efforts of the LDS Church, which has allowed researchers to trace genetic disorders through several generations. The relative homogeneity of Utah's population also makes it an ideal laboratory for studies of population genetics. The university is home to the Genetic Science Learning Center, a resource which educates the public about genetics through its website.

There are several large Mormon ancestral family organizations, notable for their longevity, quality or degree of organization, or connection to well-known deceased or currently living persons. A non-exhaustive list appears below.
