Last year I was able to finally locate my 2nd Great Grandfather Wm C Cook in the 1840 US Federal Census for Dyer Co TN. I've been reviewing that census this morning as well as looking at Tax lists for the area and researching his neighbors a bit more. This is something I revisit periodically since finding the census entry. I'm trying to determine what he and his family were doing so far out of place from where I'd expect them to be.
1839 Dyer Co Tax List Civil District 6 contains the majority of the families who are around Wm C Cook in the 1840 US Federal Census of Dyer Co TN. Something I hadn't noticed before for this tax list was that at the very end of that District is a list of abt 15 people(it continues to the next page) with a header that on says " The Following is listed by the commissioner for Double Tax". There is a Cook name listed--specifically, Heirs of John W Cook. These people are a continuation of District 6 because immediately after their listing there is a Total for District 6 row.
