I have seen a scan of the index card for his naturalization at FamilySearch, so I have his petition and certificate numbers.
My question is that the list of microfilm rolls available at the National Archive website doesn't seem to give me much help in terms of figuring out which roll I would find his packet in. The rolls seem to come in two sets -- 1-200, and 201-369. There is no indication of which roll contains packets from which year, or which certificate numbers, or any of that.
If anyone has obtained not just certificates but the actual full packet of information for an ancestor's naturalization and could give me a bit of guidance, it would be much appreciated.
