I am really interested to know why your favourites are Anne (Boleyn I presume) and Catherine Howard.
Anne, in all her biographies was not a nice person. She was arrogant, proud and vengeful, ambitious and greedy. She used her position to get what she wanted, Hampton Court Palace, for one example. She had no remorse and her complete confidence in her own powers brought her own downfall. I find her fascinating to read about, so in that way she could be one of my favourites and I firmly believe that her beheading was murder as I don´t believe for one moment the crimes she was accused of, they were just a way of paving the way for the next Queen. I, because of this have always felt very sorry for her despite her obvious failings and, in a way foolishness.
Her Cousin Catherine Howard was a silly young girl who should have known better. By that time she knew or should have known the full story of what had happened to her cousin.
She was a frivolous little wanton and if she had lived in our day would have spent most of her time reading or more likely watching love stories on TV and her mother, or in this case it was her grandmother, if she had been watchful would have put her on the pill and watched her extremely closely.
Poor little Catherine didn´t seem to have a brain in her head, and unfortunately it was this want of IQ that brought about her end, which wasn´t nice, but for those days was what usually happened to adultresses whatever level of society they belonged to. She did have her one moment of nobility at the end when she made her last declaration on the scaffold but when I think of her it is usually "that poor little fool".
