The Jackson County Alabama marriage records start with 1852. Records prior to that date are missing. I haven't searched the land records to see if she is mentioned there.

Cedar Township was cut from Madison County AR and added to Carroll County AR about 1860. John Hays bought land in Madison County that ended up in Carroll County according to the BLM website. Cedar Township Carroll County AR is contiguous to Barry County MO. Carroll County AR has two courthouses, one in Berryville, and a later one in Eureka Springs. I have searched in both.
