Searching for David Kellems

I have been working my family tree and was told by my mother that there is a David Kellems in my family. I am looking to find him or some infomation on him. I was told that he was born in 1953 to Lloyd and Martha Kellems. Martha's maden name was Abel. She had a sister named Shirley Abel who married a Evans and lived in Southern Ohio. Her parents were Virgil and Minnie Abel. Minnie was born in Owensboro Kentucky. I was told that Lloyd was in the Air Force and after he got out of the military settled in Colorado. I hope someone can help me.
