Interesting subject - I believe a lot of Anne's pics got seriously eliminated when she became persona non grata at the court after her execution but (of course) she was acceptable again after her daughter succeeded to the throne so most of the tudor pics of her actually date from her daughter's reign (although quite a lot of people would have remembered her mother - dead 20 odd years - but they wouldn't have been so precise).
Ives suggested that the most truthful one is one very like the English History one you've posted from Hever and there is a medal from 1534 with her motto "the moost happi" though her nose is damaged.
You may well have something that the first Anne Boleyn one was partly based on Mary Boleyn or even wrongly attributed as Anne rather than Mary.
There are some Holbein pictures with "Anne the quene" on them but they think the title was added in the seventeenth century - wrongly.
I would say that the first and the third portraits are of the same person - but which Boleyn sister I wouldn't know. Compare the painting of the chin - nos one and three look similar but two is much thinner, also older. I think that one might be of Mary?
Well the 2nd pic is definately anne. She was older and thinner than mary, although mary has been often seen as the more beautiful (pic no. 3 is definately her). The pic im not sure about is the first one - i think it definately looks more like mary boleyn (the woman in pic no 3) rather than anne, whom it haas been labelled as
I'd be interested in the provenance of the profile portrait (number 1); to me it looks like a far later, romanticised painting - maybe Victorian - than authentically Tudor, though similarly the portrait "of Mary" (no.3) seems later in date, with very non-16th c. eyes.A semi-profile is rare in Renaissance portraits that were meant as such rather than as parts of a larger composition, and the "pretty", rounded depiction of the face in both seems wrong for a style in which the face was presented very "flatly" in painting - contrast with the authentic image of the older, overweight Katherine of Aragon, which should be exactly contemporary, and you'll see why 1 & 3 look wrong. Anne was the younger sister, by the way, though definitely the slimmer by contemporary accounts, and perhaps crucially the darker - and the necklace on no. 1 seems far too slim & low-lying for its purpose as far as Anne is concerned; she deliberately wore wide necklaces or chokers to conceal an unsightly neck-mole. No.2 is certainly the officially accepted image of her, and the over-large pearls would have done this job well.
The second is most likly to be Anne, the B necklace and all the problem with the first and third, is Anne did not like the box on the hair, it was heavy and spanish (i.e katherine wore them) Remember Anne spent a lot of time at the French court and developed French fashion sense, so thats where I draw problems with the first and third pictures, Helen-of-joy Mary was the elder of the two, we know this for the idict creating Anne Marquis of Pembroke does not state her as the eldest of the children, and if she was it would have read, Anne eldest daughter of Thomas, (or word to that effect)
