A disciplinary council was held, and Thayre was eventually restored to full fellowship in the church. In 1838, Thayre became a member of the Adam-ondi-Ahman stake high council. In 1839, he moved with the majority of Latter Day Saints to Nauvoo, Illinois. In 1844, shortly after being made a member of the Council of Fifty, Thayre departed on a mission with Jedediah M. Grant, George A. Smith and Wilford Woodruff to campaign for Joseph Smith as President of the United States. After the death of Joseph Smith in June 1844, Thayre was part of the minority of Latter Day Saints who refused to follow the leadership of Brigham Young and the Quorum of the Twelve. When the majority of Saints departed Nauvoo for the Salt Lake Valley, Thayer remained behind in Nauvoo. In 1849, Thayre moved to Michigan. He was rebaptized into the LDS Church in September 1854 in New York. He became a member of the Reorganized Church of Jesus Christ of Latter Day Saints in at Galien, Berrien Co., Michigan on August 24, 1860. The date of Thayre's death is unknown. Some sources report that he died in 1856 in Massachusetts, but these reports conflict with RLDS Church records that report him being baptized in 1860. Genealogical confusion has also resulted because Thayre's father was also named Ezra, but unlike the junior Thayre, he usually spelled his name "Thayer". Other sources report Thayre's birthplace as being Randolph, Massachusetts instead of Randolph, Vermont. According to The Joseph Smith Papers (see http://www.josephsmithpapers.org/person/ezra-thayer) Thayre's death date is September 6, 1862.
