I've been reading about Catherine Willoughby, Duchess of Suffolk. Something I haven't been able to find is any reference to her feelings about Anne Boleyn. I know Willoughby's mother was Maria de Salinas (dear friend of Catherine of Aragon), but that Catherine Willoughby's religious attitudes came to be much closer to those of Anne than the Catholic Catherine of Aragon.
This question was sparked for me by Wendy Dunn's novel The Light in the Labyrinth, which poses Willoughby as one of Anne's supporters. Yet the version of her in The Tudors series is very anti-Anne. While I know that historical facts cannot always be gleaned by fiction, I am wondering if there is any information about Catherine Willoughby's actual feelings regarding Anne Boleyn.
