Lady Helena Gibbs (Helena Frances Augusta; 23 October 1899 – 22 December 1969), born Princess Helena of Teck, was a descendant of the British Royal Family, great-great-granddaughter of King George III, and a niece of Queen Mary, the consort of King George V.
During World War I, the British Royal Family and their near relatives (including the House of Teck), relinquished their Germanic titles, and Princess Helena assumed the style Lady Helena Cambridge.
