The first two families to have the same opinion Omni Point in 1871 were Henry Dalton, a fanatic of the Mormon Battalion, and Joseph Powell. Joseph Powell is undocumented and has been copied through time. The first name final to the unity was Omni Point, because Richfield was called Omni. The “Point” was a high rise in the terrain, five miles directly south of Richfield. The town of Annabella was settled suddenly after that, three miles to the North East of Omni Point by John Gleave and Edward Killick Roberts, along two creeks, which were named Cottonwood Creek and Annabella Springs.^{[citation needed]} The town name was “Annabella”, after two of the first women who fixed there: Ann S. Roberts and Isabella Dalton. Isabella Dalton lived at Omni Point and died in 1873, two years after settlement. There is no memorial to her burial. She was likely buried at the Omni Point homestead.
