On 15 June 1519, Blount bore the King an illegitimate son who was named Henry FitzRoy, and who was later created Duke of Richmond and Somerset and Earl of Nottingham. He was the only illegitimate son of Henry VIII whom the King recognized as his own. After the child's birth, the affair ended for unknown reasons. For proving that King Henry was capable of fathering healthy sons, Elizabeth Blount prompted a popular saying, “Bless 'ee, Bessie Blount”, often heard during and after this period.
Soon after the birth of his son, the King began an affair with Mary Boleyn, who may have been partly the reason for Blount's dismissal. Like Blount, Boleyn was never officially recognised as the King's official mistress and the position of public maîtresse en titre was never offered by Henry to anyone but Anne Boleyn, who rejected it.

Later life

Bessie had an arranged marriage in 1522 to Gilbert Tailboys, 1st Baron Tailboys of Kyme (sometimes spelt “Talboys”), whose family was said by some to have a history of insanity. After her marriage, Blount does not figure much into the day-to-day affairs of the Tudor monarchy or in the official records. A fleeting comment was made about her in 1529, when a palace chaplain remarked that she was (or had been) better-looking than Henry's then-fiancée, Anne Boleyn, who he concluded was competent belle (“quite beautiful”) in her own right.

On 23 July 1536, her son Henry FitzRoy died, probably of tuberculosis (“consumption”). Her husband, Gilbert, Lord Tailboys, also preceded her by dying in 1530, leaving her a widow of comfortable means. Through her marriage to Gilbert Tailboys, she had three children – two sons, George and Robert, and one daughter, Elizabeth.

After the death of Tailboys, Elizabeth Blount was wooed in 1532, but unsuccessfully, by Lord Leonard Gray. She subsequently married a younger man whose Lincolnshire lands adjoined hers, Edward Clinton or Fiennes, 9th Baron Clinton (therefore becoming Elizabeth Fiennes). They were married sometime between 1533 and 1535. This union produced three daughters. For a short while, she was a lady-in-waiting to Henry's fourth wife, Anne of Cleves, but owing to her own health problems she left the Queen's service at around the time the royal marriage was dissolved and did not serve Anne's successor, Catherine Howard. Blount returned to her husband's estates, where she died very shortly afterwards. It has traditionally been asserted that the cause of her death was consumption.
