Hi CJL,
I checked those records for you today. I found the marriage you wanted, I am not sure that there is any additional info. It has George Redshaw a tailor marrying Mary Wilson. Mary put her mark and George signed his name.
For the baptisms I found Sarah, Martha, George and Charlotte. Charlotte was actually baptised on the 18th May. Jonathan Redshaw is named as father to all of them. The page where Francis should have been is completely illegible and I didn't find any births for anybody around 1814. There seems to be a big chunk missing. These records are all on film. I remembered afterwards that there are a few years of printed records of St Peter's and will check that next time I am in.
I have taken copies of them all if you would like me to email them to you. They are quite hard to read though and I am not sure how well they will copy.
Pm me with you r email if you would like me to send them.
Best wishes,
Elin
