I am not sure where I first saw a mention of this article – Instagram perhaps?
Why was Jane Austen sent away to school so early?
Essentially the girls (Cassandra and Jane) were sent away to school to create space for paying students. But this article is full of information about the houses that could be Steventon (there are two possibilities), number of students at any time, number of servants (because some of them have to be housed too) and number of family members (remember two of the boys were also sent off to the naval academy).
I have read a lot of Austen biographies and I have never noticed the two different Steventon houses.
Both of the below images are from the article.
