Kathlyn across 2 official records

Each registrar publishes its own list, so these figures are read down a row, never across one. A position in one country is not comparable with a position in another, and Namewise never combines them into a single ranking. The birth counts do not compare across rows either, for a different reason: England and Wales registers roughly thirty times as many births a year as Northern Ireland, so a larger total says which registrar recorded it as much as how widely the name was given.

Kathlyn by decade in Republic of Ireland · Girls

Births registered with the name in each decade of this one list, with the number of years the list covers in that decade. Bars are scaled on births a year, which is the figure that compares between decades — a decade the list only partly covers has a smaller total without being a quieter decade. Figures belong to this registrar alone and do not carry to another.

What the record shows

Recorded by 2 registrars between 1994 and 2015, ranked in 20 years of that period.

Its highest recorded position is #211, first reached in 2005.

Its largest count from any one registrar is 20 births, registered in Republic of Ireland in 2005.

Its record falls into 3 separate stretches, with a longest absence of 1 year.

A second registrar first ranked it in 1998, and 4 years separate the first registrar to record it from the last.

Every figure here is counted from the seven official registrars Namewise holds. A position is only ever a place within the list that published it, and a record that thins or stops is a fact about what registrars printed — never about how many children received the name.

Kathlyn was ranked #211 in Republic of Ireland · Girls in 2005. These are the names immediately either side of it on that published list — a fact about the registrar's own output, not a similarity judgement.

Kathlyn and the names beside it

Two names in the same published list are measured on the same scale, in the same year, by the same registrar — so these are positions that genuinely passed each other, not a similarity judgement. Drawn from the 2,573 names with a recorded popularity standing (common, familiar, uncommon), so a name outside that set could have passed Kathlyn without appearing here.
