I had a quick look at the Tower Hamlets local history library and checked out the St Mary Stratford Bow baptisms, and didn't find anything. However, there were missing records, and I suspect they were more imcomplete than indicated. So, it's definitely worth trying them again at the LMA. What was useful though, is they suggested the best place (or perhaps only place) for Mile End records in that period is the Parish of St Dunstan, Stepney. I did try to look at those in the Tower Hamlets library, but they were just too hard to read.
It's funny that if you type "Hannah Sutton" into FamilySearch, it gives you Ann Sutton records. There was one Christened in Shoreditch, but of course, there would be no way of knowing if it's her.

Kerry, I would like to have a copy of Samuel and Anne's death certificates, if you don't mind. Thanks
