Reading the scores
Read the number as "how well this goes with Robert", not "how good this sibling name is". Style, length, first letter and sound all feed into it, and rhyming pulls it down hard. 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. Robert with Wesley or Alice does that.

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