Tobin, you should put them in touch with Abb
Gunn, World Genealogist, Clan
Gunn Society (you can google it for details). According to his information,
Lawson Gunn died in
Humphreys County, TN. So, yes, it seems he should be buried in TN, although I haven't seen information on where that might be. I haven't pushed hard on this issue yet, though. I'm currently working on filling in Abb's information on my family line, which moved from TN to OK (I'm descended from
Reuben Gunn through his sons
Lawson AND Elisha
Gunn, by the marriage of first cousins - sigh).
Anyway, Abb is probably your best lead.
