Dayna and Eileen over time

Dayna and Eileen appear together in 2 published lists, across 57 years of shared records. Eileen held the stronger position in more years in 2 of them, Dayna 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.

Each reached its own highest recorded position first in 1 of the lists they share.

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.
