Tilio
Given to 2,831 babies in France, 1900 to 2023. Every figure below is a count of birth registrations, not an estimate.
By register
By decade, every selected register together
Asked and held nothing for this name: England and Wales (1996–2025), Scotland (1974–2025), Northern Ireland (1997–2025), Ireland (1964–2025), Norway (1945–2025), Austria (1984–2025), Poland (2000–2025), Canada (1991–2024), Argentina (2012–2024), Finland (living citizens, 2026), Greenland (2002–2025). That is not a count of nought — each of those registers was searched and does not carry this spelling. Every one withholds its smallest counts, on its own rule, so a name can be real there and still absent from what they publish.
Narrow these tables
The sum at the top of each table adds counts that were not made on the same rule — the Americans publish a name only where five or more babies were given it in a year, ONS redact any name given to two or fewer in total, Finland counts living citizens rather than births. It is an indication of how widely the name is recorded, not a measurement of how many people have it.
How it is said
Not recorded. The pronouncing dictionary used here has no entry for Tilio. That does not mean the name has no settled pronunciation — it means the source is a dictionary of English words that happens to contain many names, and it is thinnest on names coined recently. Nothing is guessed here, because a guessed pronunciation of somebody's name is worse than none.
Where these numbers come from
United States, 1880 to 2025
As a boy's name, Tilio was registered 5 times in the United States between 1910 and 1919, most often in the 1910s.
England and Wales
Not in this register. Tilio does not appear in the English and Welsh figures for 1996 to 2025. ONS withhold any name given to two or fewer babies in total, so this means the name was rare there rather than unknown.
Scotland
Not in this register. Tilio does not appear in the Scottish figures for 1974 to 2025. NRS suppress any name given to two or fewer babies in a year, so this means the name was rare there rather than unknown.
Northern Ireland
Not in this register. Tilio does not appear in the Northern Irish figures for 1997 to 2025. NISRA print every name given to a baby registered there, so an absence here means the name does not appear at all between 1997 and 2025.
Ireland
Not in this register. Tilio does not appear in the Irish figures for 1964 to 2025. The CSO list a name once it has reached three babies in any single year, so this means the name never did.
Norway
Not in this register. Tilio does not appear in the Norwegian figures for 1945 to 2025. SSB list only names used by at least two hundred people in the previous year, so an absence here usually means the name was never that common in Norway rather than never used.
Sweden, 1998 to 2022
2 babies, from a register that begins in 1998. Its decades cannot be compared with the American ones, which reach back to 1880: where the two tables above put them in the same row, they are counting different lengths of record.
Source: Statistics Sweden, released under CC0, which asks for no credit at all. The registers withhold small counts on different rules — SCB withhold anything under two — and under ten before 2004, which is a different bar in the same table, and the Americans hide one given to fewer than five in a year — so a name in one table and not another may only have met different thresholds.
The Swedish bar moved in 2004. Until 2003 a name was published only if ten or more babies of that sex were given it; from 2004, two. A Swedish column that looks thin in its first years is showing that rule, not a name becoming popular. The series also stops: SCB ceased producing name statistics in 2024, so 2022 is the last year there will be. And what it counts is a tilltalsnamn — the given name a person actually goes by — rather than every name on the register.
France, 1900 to 2023
2,831 babies, from a register that begins in 1900. Its decades cannot be compared with the American ones, which reach back to 1880: where the two tables above put them in the same row, they are counting different lengths of record.
Source: Insee. Licence Ouverte / Open Licence 2.0 (Etalab). The registers withhold small counts on different rules — Insee withhold the YEAR rather than the name, pooling the births of a name given to fewer than three babies of a sex in a year into one undated record, and the Americans hide one given to fewer than five in a year — so a name in one table and not another may only have met different thresholds.
Belgium
Counted, but not dated. Tilio was given to 5 babies in Belgium, and not one of those births has a year published against it. Statbel publish one ten-year total per municipality and no year column at all, so there is nothing to date these births to. This is the whole of what they publish for this name.
Source: Statbel, licensed under Creative Commons Attribution 4.0. The registers withhold small counts on different rules — Statbel apply their threshold of five separately in each of 545 municipalities, so a name given to four babies in each of fifty towns is published nowhere.
Belgium is the only register here with no years in it, so it appears on every page as a single figure. And that figure is a sum of municipal counts that each reached five on their own — a floor with a hole in the middle rather than at the edge.
Austria
Not in this register. Tilio does not appear in the Austrian figures for 1984 to 2025. Statistik Austria suppress no name and no figure, so unlike every other register here this means the name was not given to a baby registered in Austria, rather than that it was given too few times to print.
Switzerland, 2000 to 2025
36 babies, from a register that begins in 2000. Its decades cannot be compared with the American ones, which reach back to 1880: where the two tables above put them in the same row, they are counting different lengths of record.
Source: Federal Statistical Office. Open use, source must be provided. The registers withhold small counts on different rules — the Federal Statistical Office withhold no count either — the smallest figure they publish is one baby — but they do not list every name, and about one Swiss baby in ten is given a name that is not on their list, and the Americans hide one given to fewer than five in a year — so a name in one table and not another may only have met different thresholds.
Switzerland suppresses no figure at all — a Swiss count of one is published as one — so what is missing here is never a small number. It is a name. The published lists hold 2,724 boys’ names and 2,628 girls’ names, against Austria’s 23,938 for a country of much the same size, and no rule is given for what puts a name on them. Rather than guess at the rule, here is the size of it measured: those names account for 69,993 of the 78,153 births the office reports for 2025.
Poland
Not in this register. Tilio does not appear in the Polish figures for 2000 to 2025. the Ministry left out any name given fewer than five times in a year up to 2012, and fewer than two from 2013. So an absence in the early years is a weaker statement than an absence in the later ones.
Canada
Not in this register. Tilio does not appear in the Canadian figures for 1991 to 2024. Statistics Canada publish a name only where five or more babies were given it in a year, and exclude single-letter names, so this means the name was rare there rather than unknown.
Argentina
Not in this register. Tilio does not appear in the Argentine figures for 2012 to 2024. RENAPER publish a figure only where a name was given to at least two people, so this means it was rarer than that, or was given only outside 2012–2024.
Finland
Not in this register. Tilio does not appear in the Finnish figures at all. DVV publish a name only where at least five living Finnish citizens hold it, so this means fewer than five do — not that no Finn was ever given it.
Greenland
Not in this register. Tilio does not appear in the Greenlandic figures for 2002 to 2025. Statistics Greenland suppress nothing, so — as with Austria — this means no resident of Greenland born since 2002 has the name, rather than that it was too rare to print.
The Social Security Administration publish the name on every United States birth registration from 1880 onward, and dedicate the data to the public domain under CC0. This page adds nothing to it: the counts are theirs, grouped by decade.
One gap, and it matters here more than anywhere. SSA publish a name only where five or more babies were given it in a year. A name you cannot find is not a name nobody used — it is a name used four times or fewer, and no site built on this data can see it.
Neither a meaning nor a pronunciation is recorded here for this name. Pronunciations come from the CMU Pronouncing Dictionary, which does not have every name; meanings are not on the site at all yet. Both gaps will be filled from named sources or left visible, rather than with something plausible.
