absolutely, yes, the middle one - though I should say that more recently, doubts have been cast on that one too. Some scholars think it's of Charlotte's friend Ellen Nussey. There are various theories about why Branwell painted himself out of the Pillar Portrait - that it made the portrait too crowded, spoiled the composition, or that his sisters laughed at him for making himself the tallest of them, instead of Emily.
The whole issue of paintings and photos of the Brontes is so messy and interesting in general!
For years the 'profile portrait' from the destroyed Gun Group portrait by Branwell (now in the National Portrait Gallery alongside the Pillar Portrait) was thought to be of Emily, but now it seems generally accepted it's Anne. Mrs Gaskell, who would have been able to compare the Pillar Portrait with Charlotte's actual appearance when she visited Haworth, thought it was a good likeness of her, and lots of people thought that the Richmond one was very flattering. Lots of her contemporaries remark on her bad and missing teeth, over-hanging forehead and smallness, though many people also remark on her extraordinary eyes.
Even Arthur Bell Nicholls (if I remember rightly) when he was contacted by biographers in the late 19thc, after he'd gone back to Ireland and remarried, said that one of the figures in a photo of the Pillar Portrait looked a bit like Anne but that he didn't recognise the others - meaning that the first image of the painting to be published had Charlotte labelled as Aunt Branwell!
