Thalia
Meaning
to flourish, blooming; muse of comedy
The story
Thalia is the Greek Thaleia, from thallo, "to blossom", and Behind the Name gives her two mythological posts: one of the nine Muses, presiding over comedy and pastoral poetry, and one of the three Graces. The American record kept the name quiet for a full century, a few hundred girls a decade from the 1910s onward, and then opened it up: about 3,800 girls in the 1990s, about 3,850 in the 2000s, about 3,200 in the 2010s, and about 2,600 so far this decade. Brazil's census tells the same story on its own clock, about 23,300 Thalias with a median age of twenty-one, about 9,800 of them born in the 1990s. A root that means blossoming, the muse of comedy on the label, and two national records that both turned upward in the same decade.
