Johnson County, Arkansas
"Johnson County was created from a portion of Pope County, by the Act of November 16, 1833, and was named Johnson honoring the first Territorial Judge of Arkansas, Judge Benjamin Johnson." (A Brief History, cited.)
The first BLM record I've found, indexed in Johnson is for 7 May 1838 to James K Polk which you can view here
