What the record shows

Recorded by 1 registrar between 2006 and 2025, ranked in 17 years of that period.

Its highest recorded position is #319, first reached in 2010.

Its largest count from any one registrar is 16 births, registered in Republic of Ireland in 2010.

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

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.

Mary Kate was ranked #319 in Republic of Ireland · Girls in 2010. 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.

Mary Kate 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 Mary Kate without appearing here.
