I am indexing Italian birth records from the 1800s. In almost all cases the records include first and last names and the patronymic name. For example, the first name is "Maria", a last name is "Cosmi and the patronymic is "di Francesco" or "fu Francesco". (The patronymic was important to identify people since so many people had the same name!) I have been including the patronymic name but maybe I am not supposed to? Please let me know.
