A short history of Eagar
Brothers William Walter, John Thomas, and Joel Sixtus settled the area under the direction of The Mormon prophet Brigham Young. They each acquired 160 acres of land under the homestead act. Once they received the deeds to their properties, again under the direction of Brigham Young, they each subdivided their properties to sell at a discounted rate to other church members who were also settling the area.
The first postmistress, Emma Goldsbrough Udall, wanted to name the town "Union", in a desire for eventually combining the town with other towns such as Amity and Springerville, to unite the small community. However, the US postmaster general rejected the name as too common. Therefore, she submitted the name "Eagarville" to honor the Eagar brothers. However, that name was also changed by the postmaster general to just "Eagar" sometime before December 1892 when the school district was renamed.
