Bailey

Bailey started as an English occupational surname for a bailiff, the medieval official who kept order in a manor or marketplace, and took on a second life as the outer wall of a castle, the word that still survives in London's Old Bailey. It crossed into first-name territory in the late twentieth century, aided by It's a Wonderful Life's George Bailey and a wave of surname-names for children of any gender. Currently at rank 182 in the U.S., it leans slightly feminine but stays genuinely unisex. Two light syllables, an easy smile. Approachable, contemporary, a bit windswept.
