I recently added a category for Sicilian Immigrants to the United States, with the sub Category of Alia, Sicilia. Alia is just a few miles east of Corleone, but most of the immigration from Alia was to New Orleans to work in the sugar cane fields. I also added Kingdom of the Two Sicilies as a subcategory for Former countries of Europe, because Italy was not unified until 1870, and Sicily was part of Kingdom of the Two Sicilies.
