Fiadh vs Olivia
Fiadh and Oliviacompared 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.

Fiadh and Olivia over time
Fiadh and Olivia appear together in 3 published lists, across 51 years of shared records. Olivia held the stronger position in more years in 3 of them, Fiadh 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.
Fiadh reached its own highest recorded position earlier in 2 of those lists, Olivia 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.
