(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.

FOREBEARS This was the clan name of the Lords of the Isles in medieval Scotland. There was considerable interaction between Gaelic speakers and Norse speakers in the Hebrides, and the name of the founder of the clan, Gaelic Somhairle, English Sorley, is itself of Scandinavian origin, from Old Norse Sumarlíðr “summer traveler” or “summer warrior”. The Macdonalds are the largest of the Scottish clans.
