Glenn

Glenn is a boy's and girl's baby name of Scottish Gaelic origin, from the Scottish Gaelic gleann meaning "valley" or "glen." It began as a topographic surname and transferred to given-name use in the English-speaking world, particularly in the United States, in the 20th century.

Glenn peaked in the U.S. top 50 boys' names in the 1940s and 1950s. Big band leader Glenn Miller, whose music defined the swing era, and Glenn Close, one of film's most formidable actresses, both carry the name with authority. The single-N spelling Glenn is more common in the U.S.; Glen is the predominant British form.
