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