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