The author, brother of the late Princess of Wales, succeeded to the title at his father’s death in 1992. The 9th earl has an Oxford degree in modern history and a refreshingly unprotective attitude toward his own forebears (the probable descendants of Tudor sheep-farmers with no claim to a connection with the Le Despensers of Normandy, whatever family tradition says), among whom were some very iffy characters as well as art patrons, active politicians, and military heroes. Robert, the first Baron Spencer, was perhaps the wealthiest man in England. Henry Spencer, the first Earl of Sunderland, gave Charles I the sum of £10,000 on the eve of the Civil War, then died on the battlefield, while his ruthless and over-ambitious son became politically influential but was widely disliked. Georgiana, the celebrated Duchess of Devonshire in the 18th century, was a Spencer, but her sister, Lady Caroline Lamb, was Byron’s mistress. George John, the second earl, was the patron of Horatio Nelson and built the largest private library in Europe — but nearly bankrupted his family in the process. Sir Winston Churchill was a Spencer, too. The fifth earl was Viceroy of Ireland and served often in Gladstone’s cabinet, but never succeeded in his ambition to become Prime Minister. (Apparently, the less said about the present earl’s parents and step-parents, the better; the tabloids pretty much own that subject.) And through the centuries, the family has amassed and managed and conserved its wealth, built fine homes, collected fine art (and sat for Reynolds, Gainsborough, and Sargent), and gone about its business. While the history is anecdotal, not academic (although there’s a good selected bibliography), this is a recommended treatment of one of the less-famous (until Diana) titled families in Britain. I’m also relieved to say that, despite her brother’s well-publicized disapproval of the Windsors, the late princess gets only a brief mention at the end of the book. No tabloidism here.
