] What you are saying about the Anglican parson being a gentleman and expecting to be housed in solid comfort sounds to me more like 19th century.

Well, the early 19th century is our era. To be sure, the parson had to maintain the parsonage out of his income, plus whatever the generosity of the patron, or his own family's wealth, might contribute. It would follow that the richer the living, the better the standard of accomodation. Improvements made by one incumbent would benefit all of his successors. I suspect that as the social status of the Anglican clergy rose through the 18th and into the 19th century, their residences went through a process of steady cumulative improvement.

As to those parishes which totally lacked accommodation, query how many of them were held in plurality. Query also how many were in the poorer and more sparsely populated areas of the North of England.
