Annabella is a town in Sevier County, Utah, United States. The population was 795 at the 2010 census, an increase over the 2000 figure of 603.
The first two families to settle Omni Point in 1871 were those of Henry Dalton, a member of the Mormon Battalion, and Joseph Powell. Joseph Powell is undocumented and unfortunately has been copied through time. The first name given to the settlement 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 shortly thereafter, 3 miles to the North East of Omni Point by John Gleave and Edward Killick Roberts along 2 creeks, which were named Cottonwood Creek and Annabella Springs. The town name was named "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 just 2 years after settlement. There is no memorial to her burial.
