I believe he married Marian Snyder in 1942 before he served in the US Army in France and Germany. They were divorced in 1945 and had one child. In addition to Rose and May I belive Walter had brothers Stanley, Joseph and Ed (who changed is name to Sharke at some point). He lived on the south side during the 40's and 50's as you said and would be in his 90's if he was alive today. I last saw him in the early 60's and have no contact with other members of that family.
