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.
