Although I have no information about a James Williams, I am researching a Jerusha Decker who married a Joseph Williams in Licking County. In 1866, Joseph left for MO. without his family. In 1879, Jerusha died and is buried in Harvey Cemetery in Hardin County, but Joseph is buried in Howell CO., MO.
Is this the same Joseph Wiliams? If so, do you know why he went to MO.? What made Joseph and Jerusha move to Hardin County?
