Meaning
variant of Lily, from the flower
The story
Lilly is the flower with a doubled l, and the doubling is older than it looks: about 3,000 girls in the 1920s wore it when it was simply a common spelling, not a variant. The midcentury fade bottomed near 630 in the 1970s. Then the great Lily boom lifted every spelling at once: about 17,300 in the 2000s, 23,500 in the 2010s, and 7,600 so far this decade, a real cooldown from the peak decades that the record states plainly. Lily, Lilly, Lillie and Lilliana all chart separately, and the shared flower is one of the century's biggest girls' sounds. In our records Lilly counts about 65,900 girls to 24 boys, all girls this decade. The flower has meant purity for millennia and spring for longer; the extra l means only that a family liked the balance of it, which is reason enough.

share of the girls on the register for that year, SSB’s own figure
People who have or have had a Norwegian ID number, emigrants left out, from Statistics Norway’s name statistics (release of January 2026): by year of birth for 1945–2020 (everyone born that year who was ever registered in Norway, including people who registered later and people who have since died) and by year of naming from 2021; only first names carried by 200 or more living people are listed, counts under 4 are withheld, and SSB merges spellings that differ only by letters outside the Norwegian alphabet. The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.

In Austria, 123 girls named Lilly were born in 2025, the 63rd most common name among girls that year, spellings that differ only by special characters counted together.
share of that year’s births on record
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.

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
Not on the record in Puerto Rico: that registry withholds small counts, so rare uses may sit below its floor.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown.
