The pauper cemetery in Corinth has 45 names listed in the Alcorn County Cemetery Book. pages 375-376. It also states that there are over 100 other graves marked only with rocks or sandstone.

This cemetery is next to the landfill in the Farmington Community.

There was not a Sloan listed and no Sloan child by that name in the Alcorn County Cemetery Book.

What were her parents names?

I recommend you contact the Corinth Library the Genealogical Society in Corinth and the Chancery Clerks Office in Corinth as they may more information.
