Belle’s father, Charles Harris, and grandfather Emer Harris were called to serve in the Cotton Mission in southern Utah. President Heber C. Kimball called two hundred families at a conference in the Bowery in Salt Lake City. The Harris family arrived in the mission the following month and lived in various parts of Washington County, Utah, until their release in 1864.

The Harris family purchased a ranch near City Creek, later known as Junction, Piute County, Utah.
(See Dortha B. Davenport, Junction, Utah: Its History and Its People, 1871–2004 [Publication place unidentified: By the author, 2005], 1, 9.)

At age sixteen, Harris met thirty-six-year-old Clarence Merrill, a business associate of her brother Charles Elisha Harris.

Harris and Merrill married in the temple in St. George, Washington County, Utah. Harris was Merrill’s third wife, after Bathsheba Kate Smith and Julia Felshaw.
(Clarence Merrill, Autobiography, 1908, BYU, [54], [61], [68].)

Harris moved to Richfield, Sevier County, Utah, to live with Merrill, Smith, and their eight children. Given the illegality of her plural marriage, Harris was listed as a “boarder” and “store clerk” on the 1880 census.
(1880 U.S. Census, Richfield, Sevier County, UT, 479B.)

Harris gave birth to her first child, Albert Merrill, while living in Richfield. Clarence Merrill was not present.
(“Belle Harris Merrill Nelson Berry,” 4 Apr. 1935, Kimball Young Research Notes, BYU, 2, [8].)

Harris became pregnant with her second child. At the time Smith was about two months pregnant, causing increased strain on the family’s resources and Harris’s relationship with Merrill.

Harris moved to a small home provided by Merrill in Monroe, Sevier County, Utah.
(Silas Albert Harris, History of Isabelle Maria Harris, 1861–1938 [Publication place unidentified: Dallin H. Oaks, 2005], 12.)

Harris met with apostle John Henry Smith, brother of Bathsheba Kate Smith, about her financial concerns and her thoughts of leaving Merrill. The apostle counseled her to postpone her final decision until after the birth of her baby.
(John Henry Smith, Diaries, 1874–1911, CHL, 30 May 1882; “Belle Harris Merrill Nelson Berry,” 4 Apr. 1935, Kimball Young Research Notes, BYU, 3.)

Concerned that Merrill would not be present for the birth of their second child, Harris relocated to her family home near Junction.
(“Belle Harris Merrill Nelson Berry,” 4 Apr. 1935, BYU, [8]; Harris, History of Isabelle Maria Harris, 13.)

Kingston, Piute County, Utah, bishop William King and his counselors met with Harris, Merrill, and Charles Harris at the Harris ranch to discuss a reconciliation between the couple. The attempted reconciliation was unsuccessful, and Belle Harris moved forward with divorce.

A grand jury of the Second District Court summoned Harris to appear as a witness in the investigation of Merrill’s marriages. Harris requested and was granted a postponement of her appearance on account of Horace’s poor health. Merrill went into hiding for two weeks to evade federal officials.
(Belle Harris to John Taylor, 12 Dec. 1882, First Presidency, Divorce Case Files, 1877–1918, CHL; Clarence Merrill, Autobiography, 1908, BYU, [69].)

Merrill finalized the divorce from Harris.
(Clarence Merrill, Autobiography, 1908, BYU, [69]–[70].)

Harris appeared before Second District judge Stephen P. Twiss and a grand jury. She refused to testify against Merrill, and the jury found her guilty of contempt of court.
(Beaver County District Court [Second District] Minute Book, Series 5319, Utah Division of Archives and Records Service, Utah State Archives, Salt Lake City, vol. 6, 14–17, 24–25.)

Harris arrived at the territorial penitentiary in Salt Lake City with her son Horace.
(Belle Harris, Journal, 18 May 1883.)

Utah’s territorial supreme court denied Harris’s application for a writ of habeas corpus, in which she had challenged the legality of her imprisonment for contempt of court.
