in about 1546, by an unknown artist Upon their marriage, Seymour moved into his wife's house,
Chelsea Manor in London, where she lived with her step-daughter, the 14-year-old Elizabeth. Seymour was the uncle of Elizabeth's half-brother, and the newly-wed husband of her stepmother. Now, living under the same roof as Elizabeth, Thomas Seymour began to show affection toward Elizabeth, tickling her, and slapping her on her behind as she lay in her bed, or coming into her room in his nightclothes. Her governess,
Kat Ashley, thought of this as scandalous, and reported it to Catherine. Indignant, Seymour retorted, "By God's precious soul, I mean no evil, and I will not leave it!". At first, Catherine dismissed the behaviour as innocent fun, and even joined in the behaviour on a few occasions. Elizabeth's feelings regarding this behaviour are unknown, but it was said that she bore Thomas some degree of affection and though her governess "bade him go away in shame", she found him more amusing than dangerous. Not long after Edward VI's accession, Seymour sought to court Elizabeth by writing in his suit to the princess, "If it is my good fortune to inspire in you feelings of kindness and you will consent to marriage, you may assure yourself of having made the happiness of a man who will adore you till death". Although in Elizabeth's reply she stated that "neither my age nor my inclination allows me to think of marriage", the tone of her response made it seem she was quite enamoured with Seymour's proposal. It seems impossible to know whether or not Elizabeth felt she was captivated or victimized by Seymour. Given that Elizabeth was relatively young, second in the line of succession of the English throne and Seymour's step-daughter and niece, and that Seymour was married to the dowager queen, his behaviour was considered to be highly improper, shocking, and immoral. When Catherine was pregnant in the spring of 1548, she had become concerned enough about her husband's flirtatious relationship with Elizabeth that she sent Elizabeth away to live with
Anthony Denny and his wife,
Joan Champernowne (Kat Ashley's sister), in Hertfordshire. In June 1548, Catherine and Thomas Seymour moved their household from London to
Sudeley Castle in Gloucestershire, the property granted to Seymour when he became Baron Seymour of Sudeley. In September 1548, Catherine gave birth to a daughter,
Mary Seymour. In the following days, she became uncharacteristically hostile and delusional. Thomas lay in bed with her to quiet her, but she did not get better, and died of childbirth complications, just before Elizabeth's 15th birthday. Upon her death, Catherine bequeathed all of her possessions to Thomas, making him one of the wealthiest men in England. He said he was "amazed" at her death; yet it opened up new opportunities for him, as his eye returned to Elizabeth. She avoided him, returning with her governess to her childhood home,
Hatfield House in Hertfordshire. ==Relationship with Edward VI==
