Meaning and history
From a Scottish surname derived from Gaelic blàr, meaning “plain, field, battlefield,” Blair is typically masculine in Scotland. In the United States, it became more common for girls in the early 1980s after the debut of The Facts of Life, which featured Blair Warner, then fell out of the American top 1000 two decades later before being revived by Blair Waldorf in Gossip Girl.
