Michael Osborne

(male) English form of a common biblical name (meaning ‘who is like God?’ in Hebrew) borne by one of the archangels, the protector of the ancient Hebrews, who is also regarded as a saint of the Catholic Church. In the Middle Ages, Michael was regarded as captain of the heavenly host (see Revelation 12:7–9), symbol of the Church Militant, and patron of soldiers. He was often depicted bearing a flaming sword. The name is also borne by a Persian prince and ally of Belshazzar mentioned in the Book of Daniel. Since the early 1900s it has been one of the most enduringly popular boys' names in the English-speaking world. See also Michal.

English: from the Old Norse personal name Ásbjorn, composed of the elements ás ‘god’ + björn ‘bear’. This was established in England before the Conquest, in the late Old English form Ōsbern, and was later reinforced by Norman Osbern. The surname Osborne has also been widely established in Ireland since the 16th century.
