Are you sure Mary b c 1810 (mentioned on the other thread) is a
daughter of John senior? Given that you say she married George Berry, I wonder whether the following census group is relevant in which case she is of an age to be (if anything) his sister

NB If this is connected to the Bollington baptisms then Edward and John jnr seem to have been transposed.
