Looking for WRIGHT & SCOTT

My mother in law passed away before I could get more complete family history. I have been working on my daughter's family tree for a couple of years and have never hit a dead end this early in the game. I am looking for the parents of Ervin (Smokey) Wright. He was born to William Wright and Harriet nee Scott in Wisconsin 5/28/1920. He died at Camp Douglas, Madison, Jeneau county, Wisconsin. That is all I know. Could have family in the N. Illinois area and S. Wisconsin. If there is anybody out there that can help, I really need it!!!
