I am looking for help finding a birth record for my biological grandpa. His name is Harry Owen Clark, born January 24, 1936. His mothers name was May B. Ustick, I cannot find his fathers name ANYWHERE. May still was living with her parents in the 1930 census, so I am hoping maybe I will get some info with the 1940 census comes out. But I am still hoping to find the birth record for him. I would very much appreciate if anyone has any helpful information, or what else I can do to find this info.
