Unfortunately my bounded resource contains only cemetery records in Wilkinson County MS through March 1990. However I used my subscription with Ancestry.com to lookup "Alexander Elliott" and found three matches:
MS 1860 Federal Census, Carroll County - Middleton Township, page 863
MS 1860 Slave Schedule, Carroll County - Police District 5 Township, page 311
MS 1870 Federal Census, Carroll County - Winona P.O. Township, page 635

I hope that this information helps you!
