Here is a link to another WordPress site, The Dragonhound.
It contains an exceedingly interesting and thought-provoking article about Anne Neville’s portraits (and those of a few others). The writer puts forward a very good case for the lady in blue, on the right of the illustration above, being Richard III’s elusive queen.
There is much more about portraits of the York brothers and the women around them. A fascinating read that is highly recommended.
