 "De" is also the nobiliary particle used with Spanish surnames.This can not be chosen by the person, as it is part of the surname, for example "Puente" and "Del Puente" are not the same surname.Children take the surnames of both parents, so if the couple above had two children named "Andrés" and "Ana", then their names would be "Andrés Gómez Reyes" and "Ana Gómez Reyes".
