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