One more “warning” for you when reading Pride and Prejudice. They often talk about " — — shires " or she'll mention a "Lord — —. " Here’s, what the lines are for, and what they mean exactly.
Britain's counties are called shires, you've got Oxfordshire, Berkshire, Yorkshire, Buckinghamshire... the list goes on and on. Austen doesn't want to specify a specific shire for the novel to be set in. It was quite common practice in those days, it means you can't say "Oh, this can't be true, there is no house like that in Cheshire." The Lord thing is along the same lines, Lords are famous people and they're on a register somewhere, so if Lady Catherine mentions that she knows Lord Waberly or someone (a man who really exsits in real life) then if he's asked and says that he doesn't know a Lady Catherine, then the logic of the book is lost. It just sort of saves on social awareness on the part of the author and avoids annoying any aristocracy by accidentally mentioning them.
