1 – In Portugal usually the names are pretty commons.
We usually have a combination of two names and it’s common to know people with the same combination.
Pedro, António, José, João, Maria, Carla, Paula are very common names for instance.
2 – My family name – Silva, is considered the most common in Portugal.
3- Since we usually have a combination of two family names in Portugal, the first one (my mother’s) – Domingues, is very popular in Galicia, from where it comes. The last one – Silva, nowadays is very common in the entire country, though its origin in the North of the country.
4 – My family name is geographical, thus it does not mean anything related to professions.
Although there are other names related such as Carpinteiro (carpenter), Trolha (mason), Sapateiro (shoe maker).
5 – Foreign names are not very popular among Portuguese.
The one I even remember is Elizabete.
6 – Usually when we meet someone we use the first name and last family name.
7- We may use just the surname, but always with a title (Sr.-Mr, Sra – Ms). I think only in the army the surname alone is used. Is very rude to speak to someone without a title, only in very familiar context.
8 – In Portuguese we may use as affectionate pet names: querido, amor, rolinha, fofinho/a.
