Reading the scores
The number by each sibling name is how well it fits Diego — roughly 5 to 99, higher is better. It rates the pairing, not the name on its own. 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. Diego with Rafael or Ramona does that.

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