Recorded by 2 registrars between 1987 and 2017, ranked in 11 years of that period.

Its highest recorded position is #235, first reached in 1993.

Its largest count from any one registrar is 7 births, registered in Republic of Ireland in 1993.

A second registrar first ranked it in 2017, and 30 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.

Cillin 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 Cillin without appearing here.
