I am looking for any information about the ancestry of Clarence Oliver Hough, my great grandfather. We know that he was adopted by a family member (his aunt and uncle, we believe), and that Hough likely was his birth name, but no living relatives remember anything about his parents (adopted or biological). What we do know is that he lived in Oklahoma for much of his life, married Josephine Hooker and had two children, my great aunt Sally and my grandmother Clara. He died in Lawton, Oklahoma in 1992. I have been unable to find a record of his birth or adoption. Any help would be greatly appreciated!
