Blair has 21,460 cumulative American girls on SSA record and currently sits at rank 218, which is also its modern peak reached in 2024. The chart is climbing rather than settling, with the most recent year setting a fresh high after a long mid-tier run that stretches back to the 1970s. The name's American history has been quiet but steadily upward.
The Scottish Gaelic source
Blair comes from Scottish Gaelic blar, meaning "plain," "field," or "battlefield." The original referent was topographical: a clearing or field used as a meeting or fighting ground. The surname-to-first-name transition for Blair happened gradually through the 19th and 20th centuries, with use on both genders in Scotland and earlier American adoption.
The girls' use accelerated in the United States after the 1970s and was given a sharp pop-culture lift by the character Blair Warner on The Facts of Life (1979-1988), played by Lisa Whelchel. That seven-season run anchored Blair as a girls' name in the cultural memory of Gen-X and elder-millennial parents.
The Gossip Girl moment and the unisex surname cluster
The 2007-2012 run of Gossip Girl, with Leighton Meester as Blair Waldorf, gave the name a second cultural lift just as the original Facts of Life cohort entered childbearing years. The combined effect produced the steady climb visible in the SSA data through the 2010s and 2020s. The 2021 reboot of Gossip Girl on HBO Max extended the cultural visibility into a second generation, and the recent 2024 peak suggests the multi-decade transmission is still active.
Blair travels with a cluster of Scottish and English unisex surnames that have moved onto girls in the same window: Blake, Sloane, Reese, and Quinn share the one-syllable, surname-derived structure. The cluster reads modern, slightly preppy, and confidently American.
The counter-reading
The honest concern with Blair is the cross-gender register. Blair has been used on boys in Scottish-American families for generations, and the bearer will encounter occasional male-default assumptions in written contexts. The Tony Blair political association (UK Prime Minister 1997-2007) is also still a live reference point for older generations.
