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