Aonghus and Riancompared 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.

Aonghus and Rian over time
Aonghus and Rian appear together in 1 published list, across 13 years of shared records. Rian held the stronger position in more years in 1 of them, Aonghus in 0.
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.
Aonghus reached its own highest recorded position earlier in 1 of those lists, and Rian in none. 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.

| Meaning | Not yet recorded | Traced to the Irish surname lineage behind Ryan (descendant of Riaghan/Rian) rather than a standalone root word. A popular claim that it means 'little king' is a folk etymology found on baby-name websites, not a scholarly derivation — the true root of the underlying Old Irish name is unclear. |
