Perhaps you should try some spelling variations:
abierta y » abiertas 1, abierta en
la 1860 » la 1868, a 1860
a 1820 » a 1920, a 1850, a 1827
de mas » de masa, de max, de masas
mas la » mas alla, masas la
mar a » mar y
15 de » 1 de, 12 de, 17 de
y 30 » 1 30, y 3, y 10

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 abierta y 30 de mar a 1820 ) OR ( Cabildo abierta de 15 de mas la 1860 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta y 30 de mar a 1820 ) OR ( Cabildo abierta de 15 de mas la 1860 ))*.
