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