I was astonished to learn that she had been married and widowed twice before she married the King. Particularly as she never had any children by her first two husbands in spite of being married something like a total of 14 years. Her second husband got dragged into something called the Pilgrimage of Grace, a popular uprising protesting the dissolution of the monasteries. I'd never heard of this uprising either. She had no children other than a daughter by Seymour; Katherine died within a week of giving birth. She only outlived Henry by just over a year. Her fourth husband was beheaded six months later for treason. I found myself counting on my fingers a lot while reading this book: people died quite young back then, for all sorts of natural and political reasons.
There was one part that made me laugh and I re-checked the book so that I could share it with you. It was the marriage vows of Henry VIII and Katherine:
Henry: I, Henry, take thee Katherine, to my wedded wife, to have and to hold from this day forward, for better for worse, for richer for poorer, in sickness and in health, till death us do part, and thereto I plight thee my troth.
Katherine: I, Katherine, take thee Henry to my wedded husband, to have and to hold from this day forward for better or worse, for richer for poorer, in sickness and in health, to be bonaire and buxom in bed and at board, till death us do part, and thereto I plight unto thee my troth.
And some of us women worry about having to promise to 'obey'!
As usual, I'm fascinated by strange words and had to look some of these up:
plight: pledge or promise
troth: fidelity, allegiance (variant of truth)
bonaire: cheerful and pleasant
buxom: obedient, lively, yielding
board: dinner table
