Did King Nebuchadnezzar have children and was his daughter named Fenena as appears in the Opera Nabucco by Verdi?

We know of two children of Nebuchadnezzar: a son, Amel Marduk (known as Evil-Merodach in 2 Kings 25:27), and a daughter Nitocris. Fenena was an imaginary person in Verdi’s opera. In fact the only historical character in the opera is Nebuchadnezzar himself, although he is called Nabucco.
