An archaeological dig is underway to find the location of the home built for Joseph Smith Sr. and his wife Lucy Mack in Nauvoo. Recent discoveries led to a possible site just south of the Joseph and Emma Smith Mansion House.
"You found the key to Grandma's house," Bob Smith, the dig site host and a great-great-great-grandson of Joseph and Lucy Mack Smith, said. "Working on the site, holding something they might have held before, making that connection is a positive thing."
