Thank you for responding. No that is not it. It is the microfilm that ancestry does not have. I went to a family history center and saw the Railton (Centreville)records, they are part of St Anthony's index. I must not have ordered the other reel. This was last year so they don't have it anymore. I only have a copy of the index and numbers and not the actual priest's note or marriage bann.
Thank you,
Karen
