Reading the scores
Higher means a cleaner fit with Ruby. A Top 10 sibling name can still score low here if it rhymes with Ruby or starts with the same letter. How the score works.
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. Ruby with August or Iris does that.

Common questions
What names go well with Ruby for a sibling?
For a brother: August, Silas, Kai, Leo.
For a sister: Iris, Stella, Lillian, Maeve. These share Ruby's style and level of familiarity without rhyming or starting with the same letter.
Should a sibling name match Ruby?
It should feel like it belongs to the same family as Ruby, not like a matching set. That means a shared era or style — Ruby reads as nature and vintage, so lean that way — but a different starting sound and ending. Names that rhyme with Ruby or also start with "R" get fewer points here.
Does Ruby need a sibling name of the same origin?
It helps but is not required. Another Latin name (like Ruby) gets a small scoring bonus because shared roots read as deliberate, but a strong style match with Ruby matters more either way.
How is the match score for Ruby worked out?
Each name is checked against Ruby: a shared style and era counts the most, then how close the two are in popularity, then points come off for rhyming with Ruby, sharing its "R" start, or ending on the same sound. Full detail on the NamePairings how-we-score page.
