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