Problem:Question: What was the name of the man that Paul FitzGerald claimed as his great-grandfather? Passage:In 2006, a lawsuit was filed with HMG's Department of Constitutional Affairs by Theresa Pamella Caudill, daughter of Eleanor and Maurice F. "Desmond" FitzGerald, on behalf of her nephew, a California builder, Paul FitzGerald, as claimant to be the rightful Duke of Leinster. FitzGerald purported that he is the grandson of Major Lord Desmond FitzGerald (1888-1916), the second son of The 5th Duke of Leinster, who was recorded as having been killed in action during the First World War while serving with the Irish Guards. When The 6th Duke of Leinster died, mad and childless, in February 1922, the Leinster dukedom and its considerable wealth and lands devolved upon his youngest brother Lord Edward FitzGerald, who succeeded as The 7th Duke of Leinster. Paul FitzGerald and his supporters claimed that Lord Desmond faked his death and emigrated to California (by way of Winnipeg, Manitoba, Canada) where he lived until his death in 1967. It was further claimed by Mrs Caudill that a package of documents, witnessed by the Prince of Wales and Sir Edgar Vincent, Lord Feversham, had been lodged by her father with the Crown Office of the House of Lords in 1929, and the family had been denied access to them. Mrs Caudill believed the documents included evidence that her father agreed to relinquish the title for one generation but made it clear it was to be passed down to his son, her brother Leonard FitzGerald. Instead, it was passed down through her father's brother's family. It was alleged that an archivist had acknowledged the package had once existed, but the official line was that it was now lost.

Solution:
FitzGerald purported that he is the grandson of Major Lord Desmond FitzGerald (1888-1916), the second son of The 5th Duke of Leinster, who was recorded as having been killed in action during the First World War while serving with the Irish Guards
