Perhaps you should try some spelling variations:
abierto en » abierta en, abierto y
re mario » de mario, de marion, org mario
mario e » mario de, mario a
a 1820 » a 1920, a 1850, a 1827
la re » la red, la fe
de 30 » del 30, de 0, de 20
mar a » mar y
e 31 » el 31, 1 31, 2 31

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierto en la re mario e 31 ) OR ( Cabildo abierta de 30 de mar a 1820 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto en la re mario e 31 ) OR ( Cabildo abierta de 30 de mar a 1820 ))*.
