John David Thompson
Nauvoo was not yet settled so I don't think this information is absolutely accurate but this is all the information that I have.
John Orson Thompson
Nashville is in Jackson County Iowa not Lee County.
James Brigham Thompson
Jefferson County could not be the death county if he died in Idaho Falls because that city is in Bonneville County since 1911 and before that the city's county was Bingham County.
Mary Elizabeth King
The burial date is May 22, 1903 in Vernal but the death date is only October 28, 1903. This raises many questions but I was unable to find any other information.
Surname could also be spelled Gunsolly, Gonovly, or Gunsolla.
