Napoleon Stewart born around 1870 and his wife Milly Jackson Stewart was born around 1881 are both from Wilkinson County, MS. Napoleon's father was John Stewart and his wife was Lizzy (unknown). It is said that Napoleon traveled to the MS Delta frequently and possibly had children. The same thing has been said about his father John. I am still researching. John Stewart is believed to be form Wilkinson County too but I do not have a date of birth or death record on him.
I hope this helps. I have not found out Lizzie's maiden name or if Lizzy is short for something else yet.
