(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.

Scottish and northern Irish: from Anglo-Norman French waleis ‘Welsh’ (from a Germanic cognate of Old English wealh ‘foreign’), hence an ethnic name for a Welsh speaker. In some cases this clearly denoted an incomer to Scotland from Wales or the Welsh Marches, but it may also have denoted a Welsh-speaking Scot: in western Scotland around Glasgow, the Welsh-speaking Strathclyde Britons survived well into the Middle Ages.
Jewish: this surname has been adopted in the 19th and 20th centuries as an Americanized form of various Ashkenazic Jewish surnames, e.g. Wallach.
