Reading the scores
The score ranks each pairing with Eleanor 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
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. Eleanor and Sebastian, or Eleanor and Penelope, is a good example.

Common questions
What names go well with Eleanor for a sibling?
For a brother: Sebastian, Theodore, Samuel, Julian.
For a sister: Penelope, Lucy, Lydia, Nora. All of them keep Eleanor's general feel but start and end on their own sounds, so the two names never blur together.
Does a brother or sister name need to match Eleanor?
Match the feel, not the sound. Names that are too close to Eleanor can sound like a set rather than two separate people. That means a shared era or style — Eleanor reads as vintage and royal, so lean that way — but a different starting sound and ending. Every name on this page shares at least one style label with Eleanor. Names that rhyme with Eleanor or also start with "E" get fewer points here.
Does Eleanor need a sibling name of the same origin?
No, though it can help. Another Greek name (like Eleanor) gets a small scoring bonus because shared roots read as deliberate — 6 of the names on this page are Greek too, but a strong style match with Eleanor matters more either way.
How are the sibling scores for Eleanor worked out?
Each name is checked against Eleanor: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Eleanor, sharing its "E" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
