Mary seems to have been the first person to recognise that George, her second son, had the ability to become a figure of political importance. Although she was said to have been penniless when she married his father, she somehow found the money to send him to the French court, where he learned the courtly skills, including
fencing and dancing, and gained some fluency in the French language. Having found the funds to fit him out with a suitable wardrobe, she then sent him to the English Court, where he rapidly became the new favourite of King
James I. As George rose, his mother, brothers and half-brothers rose with him: the King in 1618 said that he lived to no other end but to advance the Villiers family. Mary arranged George's marriage to the great heiress
Katherine, Baroness de Ros, who was said to be the richest woman in England. Her enemies said that she had entrapped Katherine into the marriage by arranging for her to spend the night under the same roof as George, thus tarnishing her reputation and leaving her family with no choice but to accept George's proposal. In July 1619,
Frances Coke, Viscountess Purbeck was appointed keeper of
Somerset House in London for
Prince Charles, and Mary Villiers, Countess of Buckingham, frequently stayed there, or at
Erith. In September 1622, she left court for her house at
Dalby in Leicestershire (bought from Sir Edward Noel in 1617). In May 1623, she was at
Goadby Marwood, with Viscount Purbeck, and wrote to the
Earl of Middlesex with congratulations on the birth of his daughter Frances Cranfield. The Countess of Buckingham was often at court, and rode hunting on horseback with
King James and her daughter, the Countess of Denbigh, on 19 June 1624 (the King's birthday) from
Wanstead House. When King James was on his deathbed at
Theobalds she arranged for his treatment with a plaster applied to his wrists. This angered the physician John Craig who rebuked her. For his speeches to the Countess, Craig was ordered to leave court. She lent £50 to the playwright
Elizabeth Cary, Viscountess Falkland in 1627. When the Duke of Buckingham was assassinated in 1628, it was said that she reacted to the news without any sign of surprise, as though it was something she had long expected. Whatever her private feelings may have been, she behaved outwardly after his death in a manner which struck most people as cold and unfeeling. She died four years later and was buried in
Westminster Abbey. She was a woman of formidable strength of character, but she was never popular, due to what was described as her relentless ambition and greed. She had been beautiful when young, but her manners struck the Court as loud and tactless.
