DAVID DAN TANNER (b. 8 Feb 1838) was the youngest of John Tanner's children who survived to adulthood. He was 13 years old when they moved to California, and 20 when the family all returned to Utah. "He was a fearless youth, as a result of which he was sent many places where others were reluctant to go." He married Rebecca Estella Moore in 1861 in Payson at age 23, and they had 14 children, nine born in Payson and five after they moved to Indianola. He had also married Leatha Susan Taylor in 1870, and they had 5 children, born in Payson, before this marriage ended in divorce. Dan was involved in freighting, but he was mainly in the dairy cattle business, and he moved his herd to different places trying to find the best pastures, moving his butter and cheese equipment along with them. He was reputed to be an excellent cheese maker. His mother Elizabeth wrote that she and her sister Polly frequently stayed with Dan's family and "kept dairy," at Cherry Creek, Tintic, Payson and the surrounding area, and in Spanish Fork Canyon. The summers of 1870 and 1871 were spent in the Tintic Valley where he was superintendent of the Co-op herd of cattle and horses. In the fall of 1879 he moved his family to Indianola, and they bought a 120-acre farm on the west side of the valley. They stayed here until 1905.
When they first moved to Indianola there were twenty Indian families in the valley and seven Mormon families. There was little fear of the Indians, and a number of their children attended the school provided by the white settlers. A number of the Indians, particularly the old and handicapped who lived nearby, came to the Tanner home for at least one meal a day and were always fed. The Indians spoke of David Dan as "heap good friend Tanner." He served in the bishopric of his ward for a time. He and his wife moved back to Payson in 1905 because of her ill health. David Dan Tanner died in Payson 19 Oct 1918, at the age of 80.
