Sewells of Keatchie, LA

I am trying to do some research on the Sewell side of my family. My great great grandfather was Foster Sewell from Keatchie, De Soto Parrish, Louisiana. He was born March 13, 1887 to Dick and Georgianna Sewell. He had four sisters, Eveline, Hellen, Lizzie and Dora and one brother, Robert. I do not know much else about him except I found a WWI draft card with his name on it. If we are related please contact me. This is one of the most exciting things in my life.
