I have a death certificate dated 1936 for a great uncle - James M. Quinn. In the list of survivors, one of his daughters was listed as Mrs. E.E. Wobig. His death was in the St. Paul, MN newspaper, and the Quinn family lived in the Minneapolis/St. Paul area.
Maybe this might give you some kind of lead? You can e-mail me if you'd like.
