Her SSS#............558-32-9527

She was married to MY FATHER in about 1946-1947 when
Dennis was born...
My Father is WALTER JOHN STORY
BIRTH........March 28, 1928
Birthplace...Attica, IN. USA
DEATH........NAPA, CA. USA June 1992

SO OUR BIRTH FATHERS are the same.....

I tried to order a death certificate and it wanted Father's Name......
PROBLEM is he was adopted knowingly by him and me to a step father when he turned 18 with my fathers signature and permission. So his ORIGINAL BIRTH CERTIFICATE in CA would have MY FATHER'S name on it but....

I don't know his step fathers FIRST or MIddle Name.
I only know his LAST NAME

I don't know his spouses or children's (if any) names.
I know where he went to high school and have seen his picture in year books...but I am STUCK now with the information I have....

ANY HELP would be greatly appreciated....

You can answer me here or at PeggyCA10@aol.com

THANK YOU IN ADVANCE :)
