There were quite a few Clarence Cronk(s), many of them from Canada. If you are able to add anything to specify which Clarence it could help the search. Do you happen to know about when he was born, who he married, where he might have lived or anything like that?
Here is a link to FamilySearch showing a few... maybe something looks familiar to you: Clarence Cronk - location Canada
