Growth of the Dickens families in Tennessee
All my previous disclaimers apply here. In the 1980's when I did my first research, this is the spread of Dickens families as I found it in the Census records available to me at the time. Some years may have additional households in other counties whose records were lost or unavailable back then. What you see is what I found. 
However, you can tell by the maps that the Dickens population was keeping up with the US population growth. 

The first map below shows the North Carolina Military Reservation in what we know as northern Middle Tennessee. Its dimensions were 55 miles north to south and 120 miles east to west. Revolutionary war veterans were given land grants in that area by North Carolina in lieu of monetary payments for service. Most of those grants were sold by the veterans for pennies on the dollar.

As time passed and Tennessee counties spread, thousands of  land grants and warrants were issued to citizens, causing much confusion. Land disputes between 
North Carolina and Tennessee over who owned what, continued until well into the mid 1800's.

My Dickens forefathers settled near the eastern edge of the Reservation in Smith and Jackson Counties.  Some of the family were there in the late 1790's and more of them in the very early 1800's.

The darkened counties beginning with the 1820 map are
counties where I found Dickens' counted in the Census.   
The Head of Household names appear on the next page. 
Land grants, surveys, disputes, disagreements, hardships, and existing records are all discussed at length on several Web sites and in many books. Below are some links to good information that you might like to read.

"Half of the 1820 census schedules for Tennessee are presumed lost. Of Tennessee's two district courts, records from the Nashville District still exist, while the Knoxville District records no longer exist."
