Today would have been the 100th birthday of the genealogically remarkable Infanta Alicia of Bourbon-Parma, Duchess of Calabria (1917-2017), had she not died in March. The last surviving royal born before the end of World War I (in Vienna where Emperor Karl still reigned), she was the heiress by cognatic primogeniture of the Kings of Navarre, Edward the Confessor of England, David I of Scotland, and of the Jacobite (Stuart) claim to the English and Scottish thrones if uncle-niece marriages were excluded. Since her son Carlos (1938-2015) predeceased her, her grandson Pedro Duke of Noto (b 1968), also a claimant to the throne of the Two Sicilies, is the current heir to those theoretical claims. While at 99 she was not exactly cut off in her prime, I was sorry she didn't make her 100th birthday as she came so close. (Only one person of European royal birth has ever reached 100: Infanta Maria Adelaide of Portugal (1912-2012).) Here is Infanta Alicia pictured with Queen Sofia of Spain.
She was succeeded as oldest
living European royal by the comparatively obscure Duchess Woizlawa of
Mecklenburg-Schwerin, Princess Reuss (b 17 Dec 1918).
