APELLIDOS In the Spanish-speaking world people commonly use the last name of both their father and their mother (in that order). Thus, if Pedro García Fernández and María Piñedo Saavedra have a daughter called Eva, she will be known as Eva García Piñedo. This custom is followed in all official documents, though in everyday use many people use only their first surname. When a woman gets married she usually keeps her full maiden name, rather than adopting her husband's, though she can be known by her husband's name. So, if Eva García Piñedo married Carlos Hernández Río, she could either keep her own name intact, or be known as Señora de Hernández Río. In Latin America she might also be known as Eva García Piñedo de Hernández.
In the Spanish-speaking world most people use two apellidos, the first being their father's first surname, and the second their mother's first surname: e.g. the surname of the children of Juan García López, married to Carmen Pérez Rodríguez, would be García Pérez. Married women can either use the surnames they were born with or add their husband's first surname to theirs; so e.g. Carmen Pérez Rodríguez could also be known as Carmen Pérez de García or Carmen Pérez Rodríguez de García. In this particular case she could also be referred to as la señora de García. However most women continue to use their own surnames.
