My mother-in-law is trying to find any information on her birth father. His name was James Louis Hyndrich. He was born in Jacksonville, FL around 1926. He married a woman named Ruby May Walton and they had one daughter named Sharon Ann Hyndrich who was born May 13, 1946 in Buckeye, Arizona. She remembers seeing him last at age 3. He worked for shell oil driving a truck. Last information she had was that he had three other children after she was born. Any information would be greatly appreciated.
