Hmmmm, however it is a name isn't it? I mean first and last name? If that is so, we don't translate them. If not I should . In either case thanks I should put the whatitisn't as a note at the very least.
Normally names will not be translated.
"Kafetzou" only like to explain, that the part "de Sã" means "of Saint". but it is really only an explanation what it means!
The problem is that we don't know the purpose of the translation. It seems unlikely to me that she just wanted us to write the same thing in English and French as it was in the original Portuguese.
I think you could put the translation in the note, Irini. It certainly wouldn't hurt.
