Lachlan and Ryancompared 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.

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.

Two names moving past each other in a ranking is a fact about the ranking. Namewise does not claim one name displaced the other, that families chose between them, or that either influenced the other — none of that is in this data.

A secondary reading of that root gives 'land of the lakes'. | The Anglicized form of the Irish surname Ó Riain, a patronymic from the given name Rian. The exact meaning of Rian itself remains uncertain, despite a popular but unconfirmed 'little king' gloss. |
