[9] The organization has sponsored the publication of several works on the lives of Gilbert Belnap, Adaline Knight, and Henrietta McBride and their extended family.

It was one of the first ancestral family organizations to participate in the LDS Church's name extraction program,[citation needed] in England and the United States.

[12] In 1997 as part of the sesquicentennial celebration of the Mormon Trail, the organization commemorated and dedicated a memorial marker in Ashland, Nebraska in honor of John McBride Belnap,[13] a 13-month-old child of Gilbert Belnap and Adaline Knight who died of cholera in 1850 and was buried in his father's tool chest near the Saline Ford at the confluence of Salt Creek and the Platte River along the Oxbow Trail.

[17] In addition to supporting ongoing family history research, artifact preservation, and LDS temple ordinance work, the organization makes available primary and secondary source documentation, through various web sites, on notable family members, including Sir Robert Belknap, Chief Justice of the Common Pleas of England from 1374 to 1388, Vinson Knight, early leader in The Church of Jesus Christ of Latter-day Saints, and Martha McBride Knight Smith Kimball, documented plural wife of Joseph Smith, Jr. and later Heber C. Kimball.

Under the auspices of the organization, descendants of Gilbert Belnap, Adaline Knight, and Henrietta McBride and other Belnap/Belknap relatives have met at least 48 times, starting with the first family reunion in 1904 in Hooper, Utah.
