Rotie on Family Tree Circles

I am looking for family members on my father side. My father named was Roosevelt Sanders and he was born in Louisville, Ga, September, 1927. His father name was Henry Sanders. I do not know what his mother name was as his father remarried. He had two brothers, Clark and Henry Sanders Jr. Henry had nine children. My father had two sisters, Lula Mae, and Fannie.

My father and mother married (my mother name is Janie Hill Tonkins) in March, 1944. They separated in 1948. To this union four children were born, Essie Mae, Roberta, Josephine, and Roosevelt Sanders Jr. Before my parents separated, they moved to Philadelphia, Pa and live for a while with my mother's oldest sister, Roberta Brinson. My father died in a car accident in 1982, in Akron Ohio, where he is burial.
As I learn more I will update my journal. I am looking for aunts, uncles, and cousins who can help me locate missing family members.
