Looking for birth father

My fathers name is Jimmy Johnson. He was 33 yrs old at the time of my birth. He met Shirley Salyer and they had a relationship and he got her pregnant. She moved to Sacramento California to have me , she had three other girls at the time. She kept them but gave me up for adoption. He worked at a book binding company in Kingsport, Tennesse. I know I have two more sisters. Thanks!
