The Kellys and The O'Kellys

Anthony Trollope was one of the most successful, prolific and respected English novelists of the Victorian era. Some of his best-loved works, collectively known as the Chronicles of Barsetshire, revolve around the imaginary county of Barsetshire. He also wrote perceptive novels on political, social, and gender issues, and on other topical matters.
Noted fans have included Sir Alec Guinness (who never travelled without a Trollope novel), former British Prime Ministers Harold Macmillan and Sir John Major, economist John Kenneth Galbraith, English judge Lord Denning, American novelists Sue Grafton and Dominick Dunne and soap opera writer Harding Lemay. Trollope's literary reputation dipped somewhat during the last years of his life, but he regained the esteem of critics by the mid-twentieth century.
