I have been reading this thread with interest.

Good point Philip. Do you think it might help if Jacqueline can give a list of each:
Event, place, abode noted on PR, date, actual address where they lived ....
(eg baptism, St Leonards, NIY, 1830, Bethnal Green)
It might help to look at the events laid out in order to try to understand.

Like BB I didn't really understand what the issue was with the family using a possibly larger, grander church in a neighbouring parish, and put it down to just personal preference. Or a nicer vicar perhaps.
I wouldn't be unusual for families to live "above the shop", or some addresses may be residences above with commercial/business on ground level (which may still be the case today).
