Denis and Diarmuidcompared on official birth-registration statistics and Namewise's recorded data. This page states what each name's record shows — it never picks a winner or scores one name against the other.

Head to head

The order between them changed and held in one of those lists — a change in that published list, never a claim that one name displaced the other.

Diarmuid reached its own highest recorded position earlier in 2 of those lists, Denis in 1. Each position is a place inside its own list, so this compares when they peaked and never how high.

Counted list by list. Two names in the same published list are measured on the same scale in the same year, so those comparisons are real — but positions from different lists are not, so nothing here is combined into an overall standing.
