Lady Georgia Dewhurst is described by Philip José Farmer in Tarzan Alive and Doc Savage: His Apocalyptic Life as a sister of Lord Antony Dewhurst, a figure in The Scarlet Pimpernel novels whose father was the (fictitous) Duke of Exeter. According to Farmer, she, her husband Sir Hugh Drummond, Bt. and some of his relatives witnessed the Wold Newton Meteorite strike.
Sir Hugh and Lady Drummond were the parents of John Drummond, an ancestor of Bulldog Drummond and his brother Korak.
