Blair, a surname-turned-given-name, is derived from the Gaelic word blàr, meaning "plain" or "battlefield." The name debuted in the Social Security Administration's top 1,000 for girl names in 1980, one year after the release of the hit sitcom "The Facts of Life," which featured a character named Blair Warner. It started losing steam in the 1990s, but was resurrected by Blair Waldorf, a character in the hit series "Gossip Girl," which ran from 2007 to 2012. Singer-actress Hilary Duff used Blair as a middle name for her daughter, whom she shares with husband Matthew Coma.
