I have to fill some official paperwork, and realize that they are asking me my full name, including middle name.
Being French, the system is a bit different because there is not really any middle name, but several given names ("prénoms").
It seems like in the US, people expect a single middle name, so it is unclear what to use as THE middle name when you have multiple given names.
Let's consider someone whose given names are "Alexis, Bernard, Charles" and last name "Ducatel", how do you derive the middle name, and from that the full name in official US format?
