How these were chosen

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