Reading the scores

The score ranks each pairing with Peter using our editorial rules for shared style, popularity bands, rhyme, endings and initials. It is a comparison within this list, not a percentage or a prediction of what your family will like. How the score works. Popularity figures use US SSA records for 2025. Name-history notes are shown only where a reference is recorded; origins and pronunciations can vary.

What makes a sibling set work

Common questions

What names go well with Peter for a sibling?

For a brother: Leon, Stephen, Steven, Eugene.
For a sister: Cora, Callie, Daphne, Tessa. All of them keep Peter's general feel but start and end on their own sounds, so the two names never blur together.

How closely should a sibling name match Peter?

Only loosely. A brother or sister name should sound like it was chosen by the same parents as Peter, not like half of a pair. That means a shared era or style — Peter reads as vintage, so lean that way — but a different starting sound and ending. Every name on this page shares at least one style label with Peter. Names that rhyme with Peter or also start with "P" get fewer points here.

Does the origin of a sibling name matter next to Peter?

It is a small plus, not a rule. Another Greek name (like Peter) gets a small scoring bonus because shared roots read as deliberate — 16 of the names on this page are Greek too, but a strong style match with Peter matters more either way.

How is the match score for Peter worked out?

Each name is checked against Peter: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Peter, sharing its "P" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
