Kym and Riley over time

Kym and Riley appear together in 1 published list, across 13 years of shared records. Riley held the stronger position in more years in 1 of them, Kym 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.

Kym reached its own highest recorded position earlier in 1 of those lists, and Riley 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.
