Zylphia may be a variant form of Zelpha, itself a form of Zilpah, a Hebrew female name of uncertain meaning though I’ve seen it as possibly meaning “frailty” or “drop, drip sprinkle, pour”. Zylphia may also be a variant form of Sylvia which comes from the Latin name Silvius meaning “wood, forest” from Latin silva (wood, forest) derived from Proto-Indo-European *swel-, *sel- (beam, board, frame, threshold). In Roman mythology, Rhea Silvia is the mother of Romulus and Remus, the founders of Rome, while there’s also a nymph or goddess of the forest named Silvia.
