 Possibly out of loyalty to Katherine or due to her dislike of Anne Boleyn, Elizabeth refused to take the Oath of Supremacy.When Catherine of Aragon died in January 1536, she left Elizabeth a gift of £200 for her future marriage.Around the year 1537, Elizabeth became the mistress of the poet and cousin of the late queen Anne Boleyn, Sir Thomas Wyatt (1503 – 11 October 1542).
