Manly is an unusual masculine name deriving from Old English, literally meaning 'masculine' or 'resembling a man.' As a given name, it emerged during the Victorian era when virtue names and descriptive names were fashionable. Though uncommon today, Manly experienced modest popularity in the United States in the late 19th and early 20th centuries. The name carries obvious associations with masculinity, courage, and strength. Some bearers may have been named after Manly Hall, a notable Canadian author, or in reference to Manly Beach in Australia. The direct meaning can make it feel somewhat heavy-handed in modern contexts, which has contributed to its decline. Today, it's an extremely rare choice that stands out for its straightforward meaning.
