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