I'm not sure if you will recieve this or not, but I just spoke to my father and he told me that Acie was either his Uncle or cousin.
My grandfather was Sylvester Ira Ates and was killed in 1933 in Winnfield, LA.
As far as the dates it seems that my Pa Ira and Acie were brothers. I don't know if they were close, because my grandfather was killed a couple of months after my father was born. I think they lost all ties after that.
Someone from Washington came to Louisiana and went by to visit my grandmother Thelma Joy Ates. Everyone called her Ma Joy or Sister Joy.
If you know of any other information please let me know.
