SMITH, JOSEPH, founder of the mormon sect, was born Dec. 23, 1805, in Sharon, Vt. After failing to start a colony of his sect in Ohio and Missouri, he at last settled in Nauvoo, Ill. But this failed as all others had, on account of the opposition of the people to the peculiar doctrines of the mormons. Joseph and his brother being confined in jail, were surrounded by a mob and both killed June 27, 1844, in Carthage, Ill.
