Britney is a popular girl’s name with many alternative spellings. This spelling with the -ney ending is perhaps most recognizable as the given name of pop singer and icon of the early 2000s, Britney Spears. The name is English in origin and means “from Great Britain” or “Land of the Britons.” A branch of the Celtic people, the Britons were some of England’s earliest settlers before the arrival of the Anglo-Saxons. The island is still referred to as Brittania, so if you want to give baby a name that honors her English heritage, Britney is the perfect choice.
