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