Helen Mar Kimball was a wife of Joseph Smith, founder of the Latter Day Saint movement.
Kimball was born in Mendon, New York as the third of nine children born to Heber C. Kimball and Vilate Murray. She was the only daughter to survive, and grew up being very close to her younger brother William. Being the only daughter, she was somewhat pampered by her parents . Kimball was three years old when her parents were baptized into the Latter Day Saint church in 1832. Kimballs family moved from Mendon to the church headquarters at Kirtland, Ohio in the fall of 1833. When her father was called to be an apostle of the church in 1835, he was required to travel on missions and be away from home for significant lengths of time .
