The compiler notes there seems to have been some boundary issues between Clay County, Arkansas and Greene County which are adjacent to each other in extreme northeastern Arkansas.

Actually Green county included all of what is now Clay County until Clay county was created as Arkansas's 67th county on March 24, 1873. Clay county was orgionally named "Clayton" County, after the states carpetbagger governor, Powell Clayton. After reconstruction, the countly name was shortened to Clay County to avoid the reference to the unopular carpetbagger.
