Spanish naming customs

In Spain, people have two surnames, which come from their parents. The first surname is usually the father's first surname, and the second surname is usually the mother's first surname. For example, if the father's name is Juan Pérez González and the mother's name is Ana López García, their child's full name might be Pedro Pérez López.

Sometimes people just use one of their surnames, especially in informal situations or if one of their surnames is very long or difficult to pronounce. For example, Pedro Pérez López might just go by Pedro López.

If two people get married, the woman doesn't usually take the man's last name as is common in some countries like the United States. Instead, she keeps her own last names. However, sometimes people will add "de" and the husband's first surname after their own surnames to indicate that they are married. For example, if Ana López García marries Juan Pérez González, she might start using the name Ana López García de Pérez.

It's also common for people in Spain to have middle names, but they are not usually included in legal documents or forms. So, if Pedro Pérez López had a middle name like Antonio, it wouldn't be included on his passport or ID card.

Overall, Spanish naming customs can be a little different from what you might be used to, but they're just another way that different cultures do things.
