Really?
I used to do a lot of reading on the subject (past century) and names were Edson and Manoel, even my friends from Brasil corrected me on Garrincha not being Manuel; although Manuel is used in both languages, Spanish and Portuguese and is not even close to common to use Manoel in Spanish; just like my last name Nuñez and the Portuguese language Nunes.
We have things in common that are in some sort of way twisted/reversed/changed a bit, for instance
Apellido for us is Last Name, for Portuguese speakers is Nickname? and for Spanish speakers Sobrenombre is Nickname and Portuguese is Last Name (Sobrenome?).
Theres one thing I have to ask you Roberto, what is the meaning of "Boa Suda" I don't think is something "Nice?" one of my friends told me to say it to a girl (Again ages ago) but I played it safe since I had and still have no idea of what it means. I know Boa=Buena=Good but what about the second word? (if it's spelled correct) Is it a compliment or something rude for "something" that looks very nice, ehem....
