Terry, Minnie 1878 - 6 Sept 1933 GRTV
Terry, Thomas H. 1876 - 25 Aug 1945 GRTV
GRTV, is I believe the Grantville Cemetery.
There are also about 14 other TERRYs in the book. However almost all of them died before 1900.
I suggest you contact the Jefferson County Genealogical Society, directly, and request obituary lookups for Thomas and Minnie. The obituaries will list all surviving children, and at least at town and state where they live. The society will be able to help trace any that are still in Jefferson county. Be advised that they may charge a research fee. They can also check for any marriages of the children of Thomas and Minnie.
Here is a link to their web page at the Jefferson County USGenWeb site. You can email directly from here or call...
