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