Hope this helps a little: Wilson Batez and Dora Ann Hogin married by W.D. McLeod JP, July 26, 1866 Bk 3 P 1 in Sevier County Arkansas. No Bates married in Sevier County in 1800s. Sorry I don't know where they moved to, however there are Bates in McCurtain County Oklahoma in the Bokahoma area.
A copy of marriage license can be obtain from the Sevier County Clerks Office at DeQueen, Arkanas (the Clerks office is in the DeQueen Court house.
My information is from a Transcribe hand written copy,hence it could have been spelled Bates and just transcribed as the typest saw it. Good Luck.
