Reading the scores
Higher means a cleaner fit with Rosemary. A Top 10 sibling name can still score low here if it rhymes with Rosemary 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. Rosemary with Ignacio or Cecilia does that.
