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