completely out of hand, according to the deposition of Kat Ashley, Catherine appears not only to have acquiesced in episodes of horseplay, but actually to have assisted her husband. Whatever actually happened, Elizabeth was sent away in May 1548 to stay with Sir Anthony Denny's household at Cheshunt and never saw her beloved stepmother again, although the two corresponded. Elizabeth immediately wrote a letter to the queen and Seymour after she left Chelsea. The letter demonstrates a sort of remorse. Kat Ashley, whose deposition was given after Catherine had died and Seymour had been arrested for another attempt at marrying Lady Elizabeth, had developed a crush on Seymour during her time at Chelsea and encouraged her charge to "play along". At one point she even made a comment at how lucky Elizabeth would have been to have a husband like Seymour. Ashley even told Lady Elizabeth that Seymour had confided his sentiments to her of wanting to marry Elizabeth before Catherine. After Catherine's death, Ashley strongly encouraged Elizabeth to write to Seymour offering her condolences; to "comfort him of his sorrow...for he would think great kindness therein." In June 1548, Catherine, accompanied by Lady Jane Grey, moved to Sudeley Castle in Gloucestershire. The dowager queen promised to provide education for her. It was there that Catherine would spend the last few months of her pregnancy and the last summer of her life. Catherine gave birth to her only child, a daughter, Mary Seymour, named after Catherine's stepdaughter Mary, on 30 August 1548. Catherine died on 5 September 1548, at Sudeley Castle, from what is thought to have been "childbed fever". This illness was common due to the lack of hygiene around childbirth. Catherine's funeral was held on 7 September 1548. It was the first Protestant funeral held in English. Her chief mourner was Lady Jane Grey. She was buried in St. Mary's Chapel on the grounds of Sudeley Castle, Gloucestershire, England. Thomas Seymour was beheaded for treason on 20 March 1549 and Mary Seymour was taken to live with the Dowager Duchess of Suffolk, a close friend of Catherine's. Catherine's other jewels were kept in a coffer with five drawers at Sudeley and this was sent to the Tower of London on 20 April 1549, and her clothes and papers followed in May. After a year and a half, on 17 March 1550, Mary's property was restored to her by
