I've always been intrigued by the Ladies-in-Waiting in this picture Dave, and it's only some recent research that allowed be to connect the dots and figure out the Tiaras of these ladies. Thank you for sharing it! I was just about to post about the Hon. Iris Peake, but thanks for writing about it mauriz!
Here are a few more pictures of her wearing that Tiara, which I also think comes from the Essex Family!
