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