name for a person with bright yellow hair, 1540s, from adj. form of gold + lock in the hair sense. The story of the Three Bears first was printed in Robert Southey's miscellany "The Doctor" (1837), but the central figure there was a bad-tempered old woman. Southey did not claim to have invented the story, and older versions have been traced, either involving an old woman or a "silver-haired" girl (though in at least one version it is a fox who enters the house). The identification of the girl as Goldilocks is attested only from c.1875.
[second sense fr the folk tale Goldilocks and the Three Bears]
