Delhi Darcy (1825-1899) is mentioned in "Jongor in the Wold Newton Family", a deleted portion of Doc Savage: His Apocalyptic Life by Philip José Farmer published in Farmerphile #12. It is stated that her parents were Fitzwilliam Darcy and Elizabeth Bennet, but in his commentary on the article Win Scott Eckert asserts it is more likely that she was their granddaughter, and that her parents were Fitzwilliam Bennet Darcy and Agatha Jansenius. Delhi is either way identifiable as a member of the Wold Newton Family.
Delhi Darcy married into the Gordon family of Earlston (Mr. Eckert is mistaken in suggesting in his commentary that her husband was Alexander Gordon, 5th Viscount of Kenmure and Lord Lochinvar, as research indicates that he was executed in 1716; Mr. Farmer's meaning appears to be that Delhi's husband was, rather, a descendent of the 5th Viscount through his grandson Alexander Gordon).
Mr. and Mrs. Gordon were the parents of Lochinvar Gordon, perhaps identifiable with one Perry Gordon (Mr. Farmer's handwritten geneaology has the latter name crossed out and replaced with the former), whom Philip José Farmer identifies as the grandfather of Jongor.
