Athough widely believed, it is not true that the name Loredana was first used by Luciano Zuccoli; it appears already in "Mattea", of George Sand, that was published in 1833. Loredana is the mother of Mattea. [noted -ed]
Loredana was invented by the Italian author Luciano Zuccoli for the name of the heroine in his novel "L'amore de Loredana". Apparently, it is a feminine form of the surname Loredan, known to mean "Laurel Grove."
Could this name be related to the Spanish surname Loredo? According to "American Family Name Origins", Loredo is a Spanish "habitational name from any of the places in the Basque Country and Santander province called Loredo, or Castilianized form of Asturian-Leonese Lloredo, in both cases from Latin lauretum ‘place of laurels’."
