How these were chosen
Each suggestion's share of US babies has followed a curve close to Diamond's since 1880, and its recent number of babies is within about twelve times Diamond's, so the names are in the same league. Names starting with the same letter as Diamond or with the same ending are left out, so the names go together without matching. Spellings of Diamond itself are excluded.
