Thanks everyone,
Let me do some clarifications of what I have found since.
In the 1820 Carroll County, Ms census there is a Cowles Verdun (spelling variations). It doesn't list his family by name in that census but I am assuming he was the father of Elizabeth (born 1815) who later married Francois Olivier in Catahoula Parish, La. Now I'm looking for more infor on these Verduns. If I'm looking at this correctly there is a city/town in Ms called Verdain.
Now this is what I'm wondering and actually trying to figure out. Carroll County, Ms was derived from the Choctaw Indian Recession. I'm wondering if theses Verduns/Verdains were possibly Choctaw Indians. If so, I've busted my research wide open. My grandfather was 1/4 Choctaw.
I've looked at the Choctaw Roll but, of course, it lists a lot of Indian names, doesn't help me unless I'm missing something.
This is very exciting in that I know I'm close and on the right path. I really believe these Free People of Color were Choctaw Indians who owned slaves.
