Name Rivalries
Pairs of names with a real history against each other — 11662 relationships across 10 kinds, each with its own page. Every one is drawn from a single published list, where both names were measured on the same scale, in the same year, by the same registrar — so each is a fact about that ranking rather than a similarity judgement.
Drawn from the 2,577 names with a recorded popularity standing (common, familiar, uncommon). Two names moving past each other in a ranking is a fact about the ranking — Namewise does not claim one displaced the other. Compare any two names · Most connected names
