Mack, of Scottish origin, is derived from the Gaelic 'Mac an t-sratha', meaning 'son of the spacious, wide plain'. It entered popularity as a given name in North America during the mid-20th century and has since been associated with figures such as American football coach Mack Brown and actor Mack truck driver-turned-actor, Steve McQueen. The name is short, strong, and distinctive, often favored for its simplicity and robust sound.
The name Mack experienced a significant rise and fall in popularity between 1915 and 1967, with the most notable peak being 26 years later in 1941 (10 births). However, it maintained a steady presence throughout this period, never entirely disappearing from birth records.
