I received an Email from Stanislaw Dzwonkowski who is searching for the place of burial of his grandfather. As he writes in Polish and I have not learned to speak let alone read and write in Polish we have a communications gap.

The grandfather, Adolf Dzwounkowski, died 15th Feb or 15th of Jul 1937. He had been working on a farm near the intersection of Lake Shore (643) and E Rice Rd in Centerville Twp prior to his death. As he is a Catholic it would be reasonable to assume he is buried in Mt Calvary Cemetery in Isadore.

I checked with the Leelanau County Clerks Office for a death record. They do not have a record using that spelling.
