Sibley Name Meaning
English: from the Middle English female personal name Sibily Old French Sibilie from Latin Sibilia from Greek Sibylla a title of obscure origin borne by various oracular priestesses in classical times. In Christian mythology the sibyls came to be classed as pagan prophets (who had prophesied the coming of Christ) and hence the name was an acceptable one that could be bestowed on a Christian child.
