His mother was the daughter of nobleman Georg Louis von Blomberg who served in the government of King Frederich Wilhelm III of Prussia.

Eyring received the best education available in Coburg, and about the time his father died became an apprentice drug wholesaler in Vienna.

Two of Eyring's wives included Mary Bommeli, a convert to the LDS Church who was an emigrant from Switzerland, and Deseret Fawcett, a Salt Lake City native born to English parents.

Eyring served for two years as mayor of St. George, as well as being Erastus Snow's chief assistant in the southern region of the Utah militia.

In 1887, due to attempts to arrest Eyring on unlawful cohabitation charges, he moved to the Mormon settlement of Colonia Juárez, Chihuahua, Mexico.
