Meaning
variant of Katherine; traditionally linked to Greek katharos, 'pure', though the etymology is debated
The story
Kathryn is Katherine streamlined, a spelling America made its own in the early twentieth century. The family it belongs to is ancient: Katherine has traditionally been linked to the Greek katharos, pure, though scholars note the etymology is tangled and much debated, the name reshaped over centuries by association with that word. What sets Kathryn apart is its consistency. While other spellings boomed and faded around it, Kathryn held an almost perfectly level line in American records for the better part of a hundred years, never cracking the very top, never slipping away, only recently beginning a gentle ease. It offers everything the Katherine family offers, Kate and Katie and Kat included, in a trim, unfussy six letters. Some names are weather. Kathryn has been climate: whatever the decade, it is simply, reliably there.

Austria
last on record 2020
Kathryn 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.

Kathryn is not on the 2022 record for Mexico City, where small counts are withheld at source.
The count never rose above 4 in a year, too few to chart.
Civil-registry acts in Mexico City by registration year. Counts are lower bounds (names under 6 in a month and borough are removed at source) and count name-instances, not people; compound names are split, so “Maria Jose” counts under each part. 2023, a partial extract through 3 Mar with no cell on record for this name, is excluded.

Montevideo City

The count never rose above 2 in a year, too few to chart.
Births in the department of Montevideo (not all of Uruguay) by first name and year of birth, 1940–2011, from the city’s civil registry, which writes names in capitals, almost always without accents; counted as spelling groups (accent and punctuation variants merged), nothing is withheld at source, and 2012 is excluded as a partial year.

Kathryn is not in the 2025 top 100 for New South Wales.

New South Wales (not all of Australia) publishes only each year’s 100 most popular names per sex, so a missing year means below that top 100, not rare. Source: NSW Registry of Births, Deaths and Marriages, popular baby names
New Zealand
last on record 2009
Kathryn is not on the 2025 record for New Zealand, where names under 10 in a year are excluded at source.
share of that year’s name registrations

Poland
last on record 2019
Kathryn 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)
South Australia
last on record 2016
Kathryn is not on the 2017 record for South Australia, whose registry publishes every name given that year.
share of that year’s name registrations
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.

Not on the record in Argentina and Puerto Rico: those registries withhold small counts, so rare uses may sit below their floors.
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.
