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