Maybe that explains why, while I'm a year older, you got into comics a little sooner than I did.
Lucky you! My mom always discouraged my comics reading.
By an odd coincidence with our conversation, "Daughter of the Demon" is the title of a 1931 Fu Manchu movie (one of a series of films), that is playing on TCM right now. Undoubtedly, Dennis O'Neil swiped the story title from this movie.
Another title swipe I can think of offhand is Jim Starlin's for the Warlock story in STRANGE TALES 180, "1,000 Clowns".
I'm sure there are many titles from an era that preceded us that we don't know are not original titles.
