I don't have any information on a Thornton Fry. Frank's siblings, that I have, were Eliza, Cordelia, Lizzie, Marttle, James, Irena, Ella May. Their parents were Marshall & Elizabeth. I don't know if maybe Thornton is also a sibling of Frank's or possibly a sibling of Marshall. The locations are right. I think Frank ended up in McCune Kansas. Let me know if any of this rings a bell.
