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