Fentress County must have had a lot of record loss because the records in their archives, http://tnsos.net/TSLA/archives/index.php?county=Fentress&...
generally don't start until 1900.
I'd look for Bill and Jane's land records to prove he was her husband. There aren't any probate records for when he died. The Fentress County Historical Society, http://fentresscountyhistoricalsociety.org/genealogy-informa...
might have a local death index, indexed newspaper death notices and cemetery inventories.
You can contact the Fentress County TN Genealogy, www.facebook.com/
and ask the same questions.
Looks like Jane [surname now changed to Dickson] died 1861-1869. TN didn't record deaths until the 1880s. I'd look for her deed/land records to see if husband is mentioned. No probate records in Fentress Co. during this time frame.
In 1870 her daughters Marth and Caroline were living in Fentress Co. with the Hill family.
