What the record shows

Recorded by 3 registrars between 2001 and 2018, ranked in 15 years of that period.

Its highest recorded position is #444, first reached in 2011.

Its largest count from any one registrar is 11 births, registered in England and Wales in 2008.

Its record falls into 3 separate stretches, with a longest absence of 2 years.

A second registrar first ranked it in 2008, and 10 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.

Cailyn was ranked #444 in Northern Ireland · Girls in 2011. 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.

Cailyn 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 Cailyn without appearing here.

Absence from this list does not mean the name isn't genuinely meaningful or widely used — only that Namewise hasn't sourced and reviewed that content yet. Absence from a specific year or geography above does not prove zero use there either; official statistics only publish names above a minimum threshold.
