Hi Kim, I've just noticed your scary Clytemnestra atavar!
We've seen this before with Tudor portraits! The only connection with Jane seems to be the age of the subject 17-18, which according to Starkey means that Jane was older than we've always thought! I suppose that's possible, but it's all circumstantial (including the jewellery) evidence. Even if the name Jane was there, which it isn't), there were dozens of Janes to choose from, as we've already discussed somewhere. So I'm sceptical...
Did anyone notice that Liz Hurley was having the first part of her wedding at Kate Parr's old place, Sudeley Castle?
