Keith, you did not support your assertion with a Wikipedia page, but one from a different online encyclopedia which none of us seem to have heard of, and which posts patent bollocks in its "subject of the day". However, about Yates, definitely a she, seems a reasonably well regarded historian with a post at the Warburg Institute which is affiliated with the University of London, has been dead for 35 years. She clearly divided opinion, and Trevor-Roper was on her side, which is not a good sign. You would need to read the biography by Marjorie Jones in order to understand better her veracity. But you quote one paragraph out of a whole book Keith, who knows what the rest of the book says.
