can you have a triple-barrel surname
A few British upper-class families have ``triple-barrelled'' surnames (e.g. Anstruther-Gough-Calthorpe; Cave-Browne-Cave; Elliot-Murray-Kynynmound; Heathcote-Drummond-Willoughby; Smith-Dorrien-Smith; Vane-Tempest-Stewart). Not all of those with multiple names were of the nobility; landed gentry such as George Henry Lane-Fox Pitt-Rivers consolidated the estates and wealth of several families in their multiple names. These are sometimes created when one spouse has a double-barrelled name and the other has a single surname. Nowadays, such names are almost always abbreviated in everyday use to a single or double-barrelled version. There are even a few ``quadruple-barrelled'' surnames (e.g. Hepburn-Stuart-Forbes-Trefusis, Hovell-Thurlow-Cumming-Bruce, Montagu-Stuart-Wortley-Mackenzie, Plunkett-Ernle-Erle-Drax, Stirling-Home-Drummond-Moray, and the Danish Krag-Juel-Vind-Frijs family). The surname of the extinct family of the Dukes of Buckingham and Chandos was the quintuple-barrelled Temple-Nugent-Brydges-Chandos-Grenville.
