Portuguese people are White/Southern European like the Spaniards, Italians, French and Romanians. Portugal could NEVER be considered Hispanic in modern age since the Iberian Peninsula was divided into 2 parts: Lusitania for Portugal and Hispania for Spain.
A surname is part of a personal name that is passed from either or both parents to their offspring. Customs on the format of surnames change from region to region and their use has changed over time. In most Western nations, the surname occurs at the end of a personal name, after a given name or names.
In the English-speaking world, a surname is commonly referred to as a last name because it is usually placed at the end of a person's full name, after any given names. In many parts of Asia, as well as some parts of Europe and Africa, the family name is placed before a person's given name.
