In 1761 FitzGerald is created Earl of Offaly and Marquess of Kildare in the Peerage of Ireland and in 1766 he is further honoured when he is made Duke of Leinster, becoming by this time the Premier Duke, Marquess and Earl in the Peerage of Ireland.
FitzGerald dies at the age of 51 at Leinster House, Dublin, on November 19, 1773, and is buried in the city’s Christ Church Cathedral. He is succeeded by his second (but eldest surviving) son, William, Marquess of Kildare. The Duchess of Leinster causes a minor sensation by marrying her lover William Ogilvie in 1774, but continues to be known as The Dowager Duchess of Leinster. She has a further three children by him. She dies in London at the age of 82 in March 1814.
In 1999, Irish Screen, BBC America and WGBH produce Aristocrats, a six-part limited television series based on the lives of Emily Lennox and her sisters. FitzGerald is portrayed by Ben Daniels.

Wellesley has a much less enlightened position on parliamentary reform. He defends rule by the elite and refuses to expand the political franchise. His fear of mob rule is enhanced by the riots and sabotage that follow rising rural unemployment. His opposition to reform causes his popularity to plummet to such an extent that crowds gathered to throw missiles at his London home.
Two years later Wellesley refuses a second invitation to form a government because he believes membership in the House of Commons has become essential. The king reluctantly approves Robert Peel, who is in Italy at the time. Hence, Wellesley acts as interim leader for three weeks in November and December 1834, taking the responsibilities of Prime Minister and most of the other ministries. In Peel’s first cabinet (1834–1835), he becomes Foreign Secretary, while in the second (1841–1846) he is a Minister without portfolio and Leader of the House of Lords. Upon Peel’s resignation in 1846, he retires from politics.
In 1848 Wellesley organises a military force to protect London against possible Chartist violence at the large meeting at Kennington Common.
