Reading the scores
The score ranks each pairing with Aaron 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. Aaron with Caleb or Leah does that.
