Alta Gerrey, known mononymously as Alta, is a British-American poet, prose writer, and publisher, best known as the founder of the feminist press Shameless Hussy Press and editor of the Shameless Hussy Review. Her 1980 collection The Shameless Hussy won the American Book Award in 1981. She is featured in the feminist history film She's Beautiful When She's Angry.
In 2018, 84 is the most common age for an American (U.S.) Alta who is registered female with the Social Security Administration. It is the 1, 948th most common female first name for living U.S. citizens.
In the US, it's usually pronounced AL-tah. I first heard this name after attending a 75th birthday party for an elderly woman who had a daughter named Alta. I guess the name stuck me since the woman's daughter looked a lot like my mother (I was 7 at the time).
