Barron is an English surname taken from the title baron, which came into English through the Old French baron, "nobleman" or "warrior", itself of Germanic origin. The double-r spelling keeps it clearly a surname rather than a title. Barron was a rare choice for most of this century, hovering between number 1300 and 2300 since 2015, but it jumped from number 1019 in 2024 into the US top 1000 for the first time in 2025 at number 790.
