I searched for your Jack on Genealogybank and didn't find an obit for him - there were two obits - one mentioned a Johnson and the other mentioned a Jack Gailey - that was old enough to be Your Jacks father. But none for your Jack. I did find this though: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=18...
maybe you can contact the contributor and see if they have anymore info?
