One thing in the first chapter puzzles me: The incomes of people mentioned in this book seem to be considerably lower than those JA wrote about in her novels. On page 25-6 it says that turnpike trustees had to have an income of at least 100 pounds a year, on p.17-20 that John Parker inherited an estate including "substantial farm lands worth almost five hundred pounds in annual rent", and on p.23, that Samuel Horrocks was so pleased with the man his daughter married that he settled 3000 pounds on her.
