Erna and Monacompared 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.

Erna and Mona over time
Erna and Mona appear together in 1 published list, across 42 years of shared records. Mona held the stronger position in more years in 1 of them, Erna 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.
Erna reached its own highest recorded position earlier in 1 of those lists, and Mona 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.
