Blair

From a Scottish surname that was derived from Gaelic blàr meaning "plain, field, battlefield". In Scotland this name is typically masculine.

In the United States it became more common for girls in the early 1980s, shortly after the debut of the television sitcom The Facts of Life (1979-1988), which featured a character named Blair Warner. The name left the American top 1000 rankings two decades later, but was resurrected by another television character, this time Blair Waldorf from the series Gossip Girl (2007-2012).
