"Edna, the county's largest town, is the county seat. Jackson County, one of the original counties of Texas, was formed in 1836 from the old Mexican municipality of Jackson. Both the municipality and the county were named after President Andrew Jackson and were settled predominantly by American colonists." - http://www.254texascourthouses.net/018-jackson-county.html
