You might also find it useful, if you have not already done so, to use the Bishop of Durham's Transcripts on Familysearch. At present there are only 127 images for Auckland St Andrew if you access from search records. However you can access them right up to 1851 if you find them using their catalogue: type Auckland St Andrew in the search box, click on church records and then from the list given click on Bishop's Transcripts. Scroll down until you see a camera symbol, click on it and you then have access to over 1,000 images for the parish. It is a bit fiddly but would enable you to see what a lot of the transcribers elsewhere have been transcribing from.
