The William Stuart Seeley House is a historic house in Mount Pleasant, Utah. It was built in 1861, probably by William Stuart Seeley, an immigrant from Canada who converted to the Church of Jesus Christ of Latter-day Saints with his wife before moving to Nauvoo, Illinois.[2] They relocated to Utah in 1847, and he was among Mormon settlers to move to a fort in Mount Pleasant in 1849.[2] Seeley served as the bishop of Mount Pleasant for 29 years, and he was the first mayor of Mount Pleasant.[2] He had ten children with his first wife, née Elizabeth DeHart, who died in 1872. The peace treaty of the Black Hawk War was reported signed in this house in 1872.[2] Seeley later married Ellen Carter, with whom he had two children, and Ann Watkins, with whom he had two more children. Seeley died in 1895.[2] The house has been listed on the National Register of Historic Places since July 16, 1992.[1]
