Sandy, I don't anything about Elvis Presley but I have William Washington Wiggins who m Elizabeth Sheffield (they moved to La in 1850) from AL -- some siblings did end up in MS. You can check out my family tree at:

This will give you my Wiggins and Sheffield ancestors and some of the extended families.
