Thirty days after the death of King Henry the Eighth she became the wife of the high admiral, Thomas Seymour, Earl of Sudley.

Archbishop Cranmer solemnized their union in the chapel at Whitehall, and the lord protector, now Duke of Somerset, formerly Earl of Hertford, the brother of Thomas Seymour, was the witness of this marriage, which was, however, still kept a secret, and of which there were to be no other witnesses.

When, however, they resorted to the chapel for the marriage, Princess Elizabeth came forward to meet the queen, and offered her hand.
It was the first time they had met since the dreadful day on which they confronted each other as enemies--the first time that they had again seen each other eye to eye.
Elizabeth had wrung this sacrifice from her heart.

Her proud soul revolted at the thought that Thomas Seymour might imagine that she was still grieving for him, that she still loved him.

She would show him that her heart was entirely recovered from that first dream of her youth--that she had not the least regret or pain.
She accosted him with a haughty, cold smile, and presented Catharine her hand.
