African American Walters and Edwards Families

I am searching for family of Lonnie Edwards that might still be living in Louisiana. He was born in De Soto Parish, Louisiana December 30, 1928 and died in Houston, Texas November 1986. We believe it was an automobile accident. His grandparents were Early and Mary Walters who raised him. We don't know his mother and father's names. He is the father of my oldest brother who would love to meet any family he has. Thank you for any assistance you might provide. Sincerely, Catherine
