Millie and Roisecompared 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.

Millie and Roise over time

Millie and Roise appear together in 2 published lists, across 40 years of shared records. Neither was ahead in more lists than the other.

In none of those lists did their order change and stay changed.

Millie reached its own highest recorded position earlier in 1 of those lists, and Roise 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.

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.
