BTW There is no way to determine the relationship between Antonio and Francesco Scialla on this document, is there? It is this Francesco whom I have his wife and children but cannot link him to my tree.
I think I know your answer, but I had to ask anyway.
Researching surnames Ianniello, Tamburrino, Mattora/Martora/Mattori & Scialla in Santa Maria Capua Vetere, Caserta, Campania.
The two men are very close in age, and possibly related to one another, but there is nothing specific in this document which says that they are. You're going to have to find proof of their relationship another way, I'm sorry to say.
