The Countess of Carnarvon, the real resident of Highclere Castle (which is where Downton Abbey is filmed) has started a blog. http://www.ladycarnarvon.com/
She has only just started it but has already given her readers a little insight to her light at Highclere Castle. (Apparently, she like to ride her bike with the dogs but she seems to lose one along the way.) I can’t wait to see what tidbits she might dish on next.
