Family ties?

I was checking into some of the surviving letters Jane Austen wrote to her sister. In at least one letter, she makes reference to the neighbors the St. Johns, who paid a visit.

It seems that this family lived in a house called Ashe Park. Now, of course, this was nearly 100 yrs. after my St. John ancestors show up in Barbados. But I can't find any other reference to this family.

I did, however, come across this somewhat callous observation made in one of Austen's letters:

Mrs. Hall, of Sherborne, was brought to bed yesterday of a dead child, some weeks before she expected, owing to a fright. I suppose she happened unawares to look at her husband.
