Arthur, look in USGenWeb Archives Digital Library. In Arkansas. type in Harriet Burke and you will find a marriage record for Thomas Eastland and Harriet Burke. They are our Thomas and Harriet. They got married in 1866 in Sevier Co. I think the first of their children was born in 1868 so I'm guessing that the name was changed between 1866 and '68. Thomas Sr. died in 1880.
