Head to head

Ranks are only compared within one published list and one year. Two ranks from different years, from a boys' and a girls' list, or from different registrars are not comparable, so they are not placed side by side.

Carol and Siobhán over time

Carol and Siobhán appear together in 2 published lists, across 69 years of shared records. Siobhán held the stronger position in more years in 2 of them, Carol in 0.

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

Carol reached its own highest recorded position earlier in 1 of those lists, and Siobhán 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.
