In America, this name received a boost of popularity in 2000 when a character bearing it began appearing on the television series The West Wing.
This name was borne by the heroine of Lewis Carroll's novels Alice's Adventures in Wonderland (1865) and Through the Looking Glass (1871).
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).
This is also an alternate transcription of Russian Ева (see Yeva).
This name began rising on the American popularity charts in 2008, slowly until 2012 and then rapidly after that. This might have been triggered by the folk band Everly (not associated with the Everly Brothers), which had music featured on the television series One Tree Hill in that period. It also might have simply been inspired by similar-sounding names like Everett, Evelyn and Beverly.
As an English name, it became popular due to the Fleetwood Mac song Rhiannon (1976), especially in the United Kingdom and Australia.
It is the original name of children's illustrator Tasha Tudor.
