The 2nd Earl of Cavan was insane for much of his adult life. The 7th Earl of Cavan was a general during the Napoleonic Wars, he was succeeded by his grandson the 8th Earl.[2] The 10th Earl was an army commander during the First World War and later a British Field Marshal and Chief of the Imperial General Staff.[3][4] As he died without male issue, he was succeeded by his youngest brother the 11th Earl. When the 12th Earl died, the title passed to Roger Cavan Lambart, a descendant of the 7th Earl. The title is contested by the Lambertini family, an eminent Italian family, who are descendants of the 1st Earl of Cavan.[5]
