Reading the scores
The score ranks each pairing with Silas 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 Silas for a sibling?
For a brother: August, Wesley, Ezra, Josiah.
For a sister: Ruby, Eden, Daisy, Poppy. Each one feels like it comes from the same family as Silas, but none of them rhymes with it.
Does a brother or sister name need to match Silas?
Match the feel, not the sound. Names that are too close to Silas can sound like a set rather than two separate people. That means a shared era or style — Silas reads as nature and vintage, so lean that way — but a different starting sound and ending. Every name on this page shares at least one style label with Silas. Names that rhyme with Silas or also start with "S" get fewer points here.
Should a sibling of Silas have a name from the same language?
No, though it can help. Another Latin name (like Silas) gets a small scoring bonus because shared roots read as deliberate — 9 of the names on this page are Latin too, but a strong style match with Silas matters more either way.
How is the match score for Silas worked out?
Each name is checked against Silas: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Silas, sharing its "S" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
