The story
Henrietta arrived in the English-speaking world through royalty: Henriette Marie of France married King Charles I in 1625, her name was anglicized to Henrietta Maria, and Maryland was named in her honor. Underneath sits the Germanic root of Henry, ruler of the home. American parents loved Henrietta most in the Victorian era, the 1890s marking its high point on the chart below, followed by a long, gentle century of decline. Its scientific luster comes from Henrietta Leavitt, the Harvard astronomer who, studying thousands of variable stars, uncovered the pattern that let astronomers measure distances across the cosmos; Edwin Hubble leaned on her work to show that the universe extends far beyond our own galaxy. Lately Henrietta has ticked upward again with the vintage revival, an heirloom name with an empire's history and a ruler's meaning.

The count never rose above 3 in a year, too few to chart.
Births registered in South Australia (not all of Australia) by first name and year of registration, 1944–2017, from the state’s Births, Deaths and Marriages registry, which publishes every name down to a single birth in capitals; a spelling its export repeats inside a year is counted once, and from 2018 only a top 100 is published, so the series ends at 2017.

Austria
last on record 2024
Henrietta is not on the 2025 record for Austria, which publishes every first name down to a single birth, so the name was not given there that year.
The count never rose above 3 in a year, too few to chart.
Live births in Austria by year of birth, 1984–2025, from Statistik Austria’s first-name statistics; spellings that differ only by special characters are counted together (umlauts stay apart), every name down to a single birth is published, and the count covers babies with Austrian citizenship only until 2009, every baby from 2010, and from 2015 also births abroad to mothers living in Austria. Shares divide by Statistik Austria’s count of live births from 2010, and before that by the file’s own total for the year.

Poland
last on record 2020
Henrietta is not on the 2025 record for Poland, where names given fewer than 2 times in a year are withheld at source.
The count never rose above 2 in a year, too few to chart.
First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)

Not on the record in Mexico City, Argentina and Puerto Rico: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
