This one is easy. Zsazsa debuted in the U.S. data in 1957:
- 1961: unlisted
- 1960: 8 baby girls named Zsazsa
- 1959: 12 baby girls named Zsazsa
- 1958: 5 baby girls named Zsazsa
- 1957: 6 baby girls named Zsazsa [debut]
- 1956: unlisted
The source, of course, is glamorous Hungarian-born Zsa Zsa [zhah zhah] Gábor.
It’s hard to know what caused the debut specifically, but it probably wasn’t the movies. More likely it was Zsa Zsa’s many TV appearances in 1956 and 1957. She was on The Milton Berle Show, The Herb Shriner Show, The Tennessee Ernie Ford Show, The Rosemary Clooney Show, and other shows.
Her birth name was Sári [SHAH-ree] Gábor. She was named after Hungarian stage actress Sári “Zsazsa” Fedak, whose nickname came from her young daughter’s mispronunciation of her first name.
