In most Hispanic cultures women generally keep their father's surname (maiden name) throughout their life. Some also choose to add their husband's surname to the end of their own, or in place of their mother's surname, sometimes with a de between the two surnames. Thus, a wife will generally have a different double surname than her husband, and the children will have a different double surname than either of their parents.
During the seventeenth and eighteenth centuries Hispanic naming patterns were less consistent. It wasn't unusual, for example, for male children to be given the surname of their father, while females took the surname of their mothers. The double surname system which originated among the Castilian upper classes during the sixteenth century, did not come into common use throughout Spain until the nineteenth century. Thus double surnames in use prior to 1800 may reflect something other than the paternal and maternal surnames, such as a way to distinguish one family with a common surname from others of the same surname. Surnames might also have been chosen from a prominent family or even from grandparents.
