According to the 2014 Pew Forum on Religion & Public Life survey, 1% of Oklahomans self-identify themselves most closely with the LDS Church.

[4] The history of the denomination in what would become Oklahoma begins in the 1840s and the Indian Territory Mission was created and placed under the leadership of George Miller in 1855.

In the late 1840s, George Miller, a former bishop who delayed going to the West, traveled from Winter Quarters to visit his son in Texas.

He and two other members with him, Joseph Kilting and Richard Hewitt, found construction work available in the Cherokee Nation.

They also began to teach others about the LDS Church's faith and doctrine, but antagonism forced Miller to leave in December.

After hearing misconceptions about conditions there, his party settled in Indian Territory and built a gristmill.

As early as July 1855, missionaries preached to about 400 Indians, and the Cherokee Branch was started at Croft's Spavinaw Creek mill.

By 1860, the missionaries (except John A. Richards, who had married an Indian wife) returned to Utah and the mission was discontinued.

When Matthew Dalton and John Hubbard returned to begin missionary work in 1877, they found Richards was still faithful, and they received assistance from him.

Although he had contracted malaria, he carried on the work and was assisted by John Richards, and later by additional full-time missionaries.
