Thomas Seymour

Seymour and Catherine Parr became romantically involved after the death of her second husband, but then King Henry took an interest in Catherine, and Seymour had to step aside. Catherine became Henry's sixth wife, and after he died, she did marry Seymour but shortly became pregnant, and she and her baby both died when she gave birth.

Thomas (the Lord Admiral) and his brother Edward (the Lord Protector of England) wielded great power in England, through their nephew King Edward VI of England who was still a child when he came to the throne, but Thomas was ambitious and wanted to marry the Princess Elizabeth, later Elizabeth I of England, to stay on top. His sexual misconduct with her while she lived with him and her step-mother caused her to be sent away. He was eventually executed for over-reaching in the power game, trying to wrest control of young Edward the king from Thomas's brother.
