Keelin and Marilyn over time
Keelin and Marilyn appear together in 1 published list, across 14 years of shared records. Keelin held the stronger position in more years in 1 of them, Marilyn 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.
Marilyn reached its own highest recorded position earlier in 1 of those lists, and Keelin 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.
