Trying to break a few brick walls......

I'm doing research on behalf of a friend, who's descended from Reconstruction-era ancestors & enslaved Louisiana ancestors.

I have names of 5 of his ancestors, but no death records and counties of birth for some of them.

*MNU=Maiden Name Unknown.*

They are:

1. Jesse Prentice Atkins (born in 1897, Louisiana - died on 31 October 1961, Chicago, Cook County, Illinois);

2. Jesse's mother, Mary H. Hummings (born in 1872, Louisiana-) - his father, Asa H. Atkins, later married Florence N. (MNU);

3. Asa's parents, Henry Atkins (born in 1850, Mississippi - died in Louisiana) & his girlfriend, Bettianna MNU (born in 1854, Mississippi - died in Louisiana). Henry's race was mulatto & his parents were from North Carolina.

All I know is, they lived in (at some point) East Carroll County, Louisiana (formerly East Carroll Parish).

Everyone else, besides Henry, was black.

All I've found, so far, are Census records (since I'm not an Ancestry subscriber, the only site I use is FamilySearch).

So, what are their counties of birth & death dates/death locations?
