Reading the scores
The score ranks each pairing with Eithan 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
The test is calling both names across a park. They need to start with different sounds so they do not blur together, be about equally well-known so one does not feel like an afterthought, and share a style so they sound like a pair you picked on purpose. Eithan with Isaiah or Hannah does that.

Common questions
What names go well with Eithan for a sibling?
For a brother: Isaiah, Josiah, Adriel, Levi.
For a sister: Hannah, Genesis, Leah, Noa. They were chosen because they sit close to Eithan in style and popularity while sounding clearly different from it.
Does a brother or sister name need to match Eithan?
Only loosely. A brother or sister name should sound like it was chosen by the same parents as Eithan, not like half of a pair. That means a shared era or style — Eithan reads as modern and biblical, so lean that way — but a different starting sound and ending. All 24 names here share a style label with Eithan. Names that rhyme with Eithan or also start with "E" get fewer points here.
Should a sibling of Eithan have a name from the same language?
It is a small plus, not a rule. Another Hebrew name (like Eithan) gets a small scoring bonus because shared roots read as deliberate — 17 of the names on this page are Hebrew too, but a strong style match with Eithan matters more either way.
How is the match score for Eithan worked out?
Each name is checked against Eithan: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Eithan, sharing its "E" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
