Many of these are taken from placenames and are preceded by 'de'. It is traditional to use the mother's surname as well as the father's so the son of Juan Garcia and Maria Sanchez could be Luis Garcia y Sanchez with the father's surname coming first, but the mother's is not always used. Unmarried women use the same system but on marriage, often add their husband's paternal surname (preceded by 'de') to their own and usually drop their maternal surname.
