I found a court case at FamilySearch that involved land that Thomas Jones of White Co., Tennessee, owned at the time of his death. The land was being sold, so there was a need to confirm his heirs. This was not taking place a few months after his death, but over 25 years after he had passed. Some of his children were deceased by that time as well, which necessitated naming their children, and—in cases where a grandchild was deceased—their surviving children.
This is a lot of great information for anyone researching this family. Thomas' wife, Rebecca Hitchcock Jones, was a sister to my 3rd-great-grandfather, James P. Hitchcock. The file includes 12 children, 22 grandchildren (representing the 6 deceased children), and 10 great-grandchildren (representing the 2 deceased grandchildren).
I extracted the information on the heirs from the file and have organized it in a spreadsheet, in which I also included the source citation. I plan to save it as a PDF and attach it to Thomas Jones' profile within my family tree at Ancestry.
