Coffman Family

I have been trying to find a Delmer or Delmar Coffman who was the son of Abraham Coffman and brother of Walter Coffman.
The last I heard he was in Denver Colorado but he has since died but not sure when or where he is buried. Also, I do not know anything about his family( wife, kids).
He was born in Kansas around 1908.
Would like any info anyone might have about him and his family along with any pictures
