On people with no surname, the 1813 Napoleonic Decree [Municipal Archives]

On June 11th, 1813, a Napoleonic decree stating dispositions on how to deal with people without a family name was published, these are the salient points:

1. Those living in the kingdom [of Italy] that do not have a surname or family name must adopt one and give a statement to the civil officer of the town where they reside within 3 months of this decree.
2. Foreigners coming to live in the kingdom and without a family name must do the same within 3 months of their arrival.
3. The family name that a father or other senior paternal ascendant adopt will be valid for all his children. In his statement the father or ascendant will mention all the children and descendants and where they live.
4. For minors without paternal ascendant, the statement will be given by their legal guardian.
5. Members of a family without living ascendant will choose a surname common to all of them, if they disagree the surname will be determined by the Mayor. Family members that are absent will comply with the decision taken.
6. Names of towns, forts and other places that are famous for battles or for other episodes of public and general interest will not be used as surnames.
7. Transgressors will be fined 100 lire and will be given a surname by the Mayor of the town they live in.

I have found in a Municipal Archive a few examples of these statements

In this first one the declarant is Geltrude "figlia della pietà" [the Pietà of Venice was an hospital founded in the XIV century that took in abandoned or very poor babies, and these children were usually known as "della Pietà or del luogo Pio di Venezia" on various documents. It almost acted as a surname, but it wasn't really. They were sent to other towns sometimes to be taken care of]. Geltrude is 19 years old and she declares, with the Mayor and Angela wife of Lorenzo Giusti, her tutor, that she wants to take the surname De Giusti.

Second example, the Mayor declares that in the house of the nurse [a wet nurse  for the baby, probably] Maddalena wife of Beniamino Larese there's a 4 year-old girl named Norberta, and that she will be taking Larese as her surname.

Last one, the Mayor again declares that Caterina Lovisatti has a baby that is her own natural child. She's 5 years and 2 months old and named Domenica, but without a surname. They decided that the baby will take the surname Lovisatti.









Was this decree successful in getting rid this problem of not having a surname?
I'm sure it helped, but I noticed it was followed by other similar decrees during the Austrian rule and I noticed even in later years there were people called "della Pietà di Venezia" and similar, and so I think it wasn't, in the end.
