Reading the scores
The number by each sibling name is how well it fits Peter — roughly 5 to 99, higher is better. It rates the pairing, not the name on its own. How the score works.
What makes a sibling set work
A sibling set works when the names feel related but not identical: a shared era or style, but different opening sounds and different endings, and no rhyme. Peter with Leon or Margot does that.

Common questions
What names go well with Peter for a sibling?
For a brother: Leon, Charlie, Abel, Richard.
For a sister: Margot, Cora, Charlie, Callie. These share Peter's style and level of familiarity without rhyming or starting with the same letter.
Should a sibling name match Peter?
It should feel like it belongs to the same family as Peter, not like a matching set. That means a shared era or style — Peter reads as vintage, so lean that way — but a different starting sound and ending. Names that rhyme with Peter or also start with "P" get fewer points here.
Does Peter need a sibling name of the same origin?
Not really — Peter's origin isn't recorded, so the score leans on style and sound instead, 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.
