As far as I can see, there is no will. I know there have been genealogies on this family. I did a Web search under Thomas Jamison Jane Dickey and found one of the Dickey family that has some good information.
I think his grandson, Love Jameson, a prominent Christian preacher (Disciples of Christ) may have written one.
The best bet on records is the Madison-Jefferson County public library or any place else with microfilms. All Jefferson County currents are in the deep freeze pending restoration after a courthouse fire.
