Seosamh appears in 2 of the published lists Namewise holds. The longest record is Republic of Ireland · Boys, which has ranked it in 27 years beginning in 1964, and has registered 106 births with the name.

Seosamh 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.

Seosamh by decade in Republic of Ireland · Boys

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.

Where Seosamh is officially recorded

2 official registrars have recorded Seosamh, between 1964 and 2025, in 28 of those 62 years. Each registrar publishes for its own population on its own methodology, so the positions below are each one country's own ranking and are not comparable with one another.

Registrar	Recorded	Years	Its own highest position
Republic of Ireland	1964–2025	27	#214 in 1964
Northern Ireland	2016–2022	3	#392 in 2020

Its high point came 56 years earlier in Republic of Ireland (1964) than in Northern Ireland (2020).

No registrar recorded it for 6 years after 1986; it appears again in 1993.

What the record shows

Recorded by 2 registrars between 1964 and 2025, ranked in 28 years of that period.

Its highest recorded position is #214, first reached in 1964.

Its largest count from any one registrar is 6 births, registered in Republic of Ireland in 1996.

Its record falls into 16 separate stretches, with a longest absence of 6 years.

A second registrar first ranked it in 2016, and 52 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.

Seosamh 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 2,577 names with a recorded popularity standing (common, familiar, uncommon), so a name outside that set could have passed Seosamh without appearing here.
