The first two families to settle Omni Point in 1871 were Henry Dalton, a member of the Mormon Battalion, and Joseph Powell.

The "Point" was a high rise in the terrain, five miles directly south of Richfield.

The town of Annabella was settled shortly 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 settled there: Ann S. Roberts and Isabella Dalton.

Isabella Dalton lived at Omni Point and died in 1873, two years after settlement.

[citation needed] According to the United States Census Bureau, the town has a total area of 0.6 square miles (1.5 km2), all land.
