Burnham Kimball Drake

Burnham Kimball Drake is my Mother's Dad. Her name is Margie Dolores
(Drake) Oelke.
He was 21 when she was born in 1955. He was a student at a college in
San Francisco. My Grandmothers name was Margaret Martinez (deceased).
The last time my Mom saw him was when she was three. His buddies called
him Burnie. He was tall with red hair. He had some tattoos with one being
his social security number. I have been searching for him in case he
wanted to find my Mom. If he doesn't then she won't have to face
rejection again.
If anyone can help me I would be very grateful. 

Thank you,
Carrie Collier
