Born George Mason, he was the son of Alan Mason, who represented County Waterford in the Irish House of Commons, by Lady Elizabeth, daughter of John Villiers, 1st Earl Grandison.
He was educated at Eton.
He became known by the courtesy title Viscount Villiers when his mother was elevated to an earldom in 1767. In 1774 he was returned to the British House of Commons for Ludlow, a seat he held until 1780. In 1782 he succeeded his mother in the earldom.
This was an Irish peerage and gave him a seat in the Irish House of Lords but not in the English House of Lords.
Three years later he was sworn of the Irish Privy Council. Lord Grandison married Lady Gertrude, daughter of Francis Seymour-Conway, 1st Marquess of Hertford, in 1772.
They had one daughter. The Countess Grandison died in Switzerland in September 1793, aged 42.
Lord Grandison survived her by seven years and died in July 1800, aged 49.
As he had no sons the earldom died with him. Their children included Henry Villiers-Stuart, 1st Baron Stuart de Decies and William Villiers-Stuart.
14th Parliament of Great Britain.
