I didn't find anything for Stephen Durnan there at all. These records are arranged by soundex. Durnan is D655.

I did find a few Durnins and Durnans, and some others that were kind of close which caught my eye. I'll put the ones that I found interesting here. The third one down is interesting only because of the McGahan surname of the witness.
Edit: In upgrading this board, the files of these Durnan naturalization records has been lost. I have no other copy of them. My apologies.
