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.

Mary and Monica over time

Mary and Monica appear together in 3 published lists, across 150 years of shared records. Mary held the stronger position in more years in 2 of them, Monica in 1.

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

Mary reached its own highest recorded position earlier in 2 of those lists, and Monica 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.
