Densford family? indiana and kentucky

I am new to genealogy, especially using the internet.I am looking for any information about my grandfather Elmer Jackson Densford.His birthdate is Sept 10, 1925.His mother was Lula Rae Crowder (born Feb 25, 1910) and I believe she was never married to his father, William Densford.My father was put up for adoption in the 1950's after a divorce and legal issues with his parents but he was able to locate his parents, and 2 brothers and his sister.There is still one brother un-accounted for.I believe Elmer's family was from Kentucky.Any information on the family would be appreciated, would really love to learn more about my dad's "real" family.Thanks!
