military historian B. H. Liddell Hart, soldier and translator C. K. Scott Moncrieff, evolutionary biologist John Maynard Smith, astronomer Robert Hanbury Brown, actresses Kristin Scott Thomas and Helena Bonham Carter (the last of whom has said the hyphen is optional, and indeed several of her relatives use it in their names), and comedian Sacha Baron Cohen (whose cousins, psychologist Simon Baron-Cohen and film-maker Ash Baron-Cohen, use the hyphen in their names). In Wales, many families have double-barrelled surnames. The preponderance in Wales of only a few surnames (such as Jones, Williams, and Davies) led to the usage of double-barrelled names to avoid confusion of unrelated but similarly-named people. Lloyd George, Vaughan Williams and Llewelyn Davies are examples of this phenomenon. A few British noble or gentry 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; Twisleton-Wykeham-Fiennes). These indicate prima facie the inheritance of multiple estates and thus the consolidation of great wealth. These are sometimes created when the legator has a double-barrelled name and the legatee has a single surname, or vice versa. Nowadays, such names are almost always abbreviated in everyday usage to a single or double-barrelled version. For example, actress Isabella Anstruther-Gough-Calthorpe calls herself Isabella Calthorpe. There is at least one example of an unhyphenated triple-barrelled surname: that of the Montagu Douglas Scott family, to which the Dukes of Buccleuch belong. 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, Lane Fox Pitt-Rivers, and Stirling-Home-Drummond-Moray). The surname of the extinct family of the Dukes of Buckingham and Chandos was the quintuple-barrelled Temple-Nugent-Brydges-Chandos-Grenville. Captain Leone Sextus Denys Oswolf Fraudatifilius Tollemache-Tollemache de Orellana Plantagenet Tollemache-Tollemache is sometimes incorrectly quoted as the man with the most ever "barrels" in his surname (six). The UK Registry Office confirms that his surname was 'Tollemache-Tollemache' and the other names are forenames. Traditions in Iberian Peninsula In Spain, surnames are strictly regulated by the Civil Code and the Law of the Civil Registry. When a person is born, the law requires them to take the first surname of the father and then the first surname of the mother. Thus, when D. Julio Iglesias de la Cueva and Dª Isabel Preysler Arrastía had a son called Enrique, he legally was Enrique Iglesias Preysler. On the other hand, actual double-barrelled names exist (called apellidos compuestos), such as Calvo-Sotelo or López-Portillo. For example, Leopoldo Calvo-Sotelo y Bustelo is the son of Leopoldo Calvo
