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