Joie Ray

I am trying to find any surviving relatives of Joie Ray, the great American miler of the 1920's who represented the Illinois A.C., was a 3-time Olympian and 7-time winner of the Wanamaker
1-1/2 Mile at the Millrose Games. He died May 15, 1978 in Benton Harbor, Michigan. Any pertinent information will be appreciated.
