 For example, if José García Torres and María Acosta Gómez had a child named Pablo, then his full name would be Pablo García Acosta.One family member's relationship to another can often be identified by the various combinations and permutations of surnames.In some instances, when an individual's given name and first family name are too common (such as in José Luis Rodríguez Zapatero and Mario Vargas Llosa), both family names are used (though not necessarily both given names).
