I didn't mention that part, sorry, I was focused on the fact that the church was in the background before it was even meant to have been built. The 1830-1840 pic of the house being 'just built' looked exactly the same as it does today, i.e. steps up to 'ground' floor with lower floor beneath ground. My suspicion is that this was the date the original house was refurbished to become habitable again, but any sinking or burying had already taken place before this date. I usually assume that any buried building has to be at least 200 years old (needs to predate 1812 at least) to be buried by whatever event took place. My theory is that buildings like this were originally built at ground level pre 1812 and were affected by the global event we are all discussing. At some stage after the event these partly buried buildings are refurbished to make them habitable and this is then announced as the date the building was actually built.Was the current underground floor above ground in the picture? Did I miss something?
