In ch. 39, Col. Brandon offers Edward, via Elinor, a rectory worth £200 a year. Shapard's annotations say that 'rectory' specifically means that the tithes all go to the rector, rather than being split with the patron. This seems to me to imply a smaller populace, since the total tithes are so low. However, Mrs. Dashwood says that Delaford is a large village, that will have some small house within it for her family.
