Peter Stewart states that Alberto di Parodi was Marques of Gavi. However the web-site which was referred to by Henry Soszynski as a follow up to the post for more information on Alberto'sancestry, (See http://genealogy.euweb.cz/italy/obert.html), says that Alberto's 1st cousin (another Alberto, son of his father's younger brother Guido), was Marques of Gavi. So there may be some doubt as to whether this Alberto was Marques of both Parodi & Gavi.
