Must be Benoni, not Beroni.
I don't know where Port Wollach is - where did you get this placename from? Is it possible to show us a scan of the document?
Do you know if his family were CoE? There are some church records on familysearch (a minority are name indexed, so a lack of result from searching from the top screen does not mean they can't be found - in many cases you will have to check parish by parish, however)
