I want to know the answer to the following question:
Who was de Melo's second marriage to?
All the background I'm provided with is that "The Queen consort of Portugal, Archduchess Maria Anne Josefa of Austria, was fond of Melo; and after his first wife died, she arranged the widowed de Melo's second marriage to the daughter of the Austrian Field Marshal Leopold Josef, Count von Daun.". Is that enough to answer the question?
Answer: yes
