Our Great Uncle, Mom's Mother's Brother, Barton Pat Miller 11/28/1892 to 2/01/1974

This is Mom's Uncle Barton Pat Miller. He lived to be 82 years old! He died in 1974? He served in World War I? It is surprising we never heard of him? Was he married? Where did he live? What did he do for a living? More ancestor mysteries to solve! Strange we only lived 30 miles away and did not know our relatives??
