As the Dowager Queen, Katherine was not suppose to remarry without the King’s and the council’s permission. Katherine and Thomas decided to marry without anyone’s permission, and they married well before the allotted mourning period.
I have read that Thomas actually tried to get the king to choose a wife for him. He had a friend ask Edward who he would choose. Edward at first spoke of Mary, then Anne of Cleves. After rejecting both of these women, Edward brought up Katherine’s name. Of course, Seymour was interested in that choice. Later, and here the author says, when Edward was convinced that the match he proposed had come to fruition, he wrote Katherine a letter in which he thanked her “for the gentle acceptance of our suit.” I found this story in Divorced, Beheaded, Survived, by Karen Lindsey. She listed a bibliography of books and papers from which she gathered her info, but she wasn’t specific as to what quote came from where and/or when it was written. Maybe someone else knows more about this?

We have had a tremendously horrifying tragedy here in America today. A young man first shot his Mother, went to the school where his Mother taught, killed 20 children between the ages of 5 and 10. If my answer doesn’t make much sense Boleyn, it is because I have been listening to the news. They along with the president are crying as they speak. And I feel like a blubbering idiot. This is heartbreaking.

Ok So we know about Katherine Parr’s marriage to Thomas Seymour , not even 4 months after Henry’s death, in which there was a huge indignance from the court, that she should marry so soon. But was it so wrong? After all she married Henry only a matter of months after Latimer’s death.
I suppose I can a see a point here in the sence that she was Queen Dowager and as such it would have been better for her to have shown the proper reespect for Henry’s death and gone through a year of mourning perhaps, but why should she? To be honest she was probably glad to see the back of the tub of lard.

I think the difference was Henry was the king with all that it entailed. His will was supreme and KP really couldn’t come up with a suitable reason as to why they couldn’t marry as quickly as possible.

But to disrespect the centuries of royal tradition and marry in haste as Princess Mary had…well whole new can of worms. Not just blowing off Henry’s memories but allying herself to one of Jane’s brothers when both opf them had been excluded from the regency council appointed by Henry. That was a not too subtle first thrust in the Seymour boys game to control the king.

Perhaps CP is more attractive than her portraits suggests. She caught the eye of Henry who was naturally drawn to pretty and or charming women. Thomas had high standards for himself and CP had been married twice before it seems maybe that she was capable of Thomas loving her.
