de mao » de maio, de mano, de max
a 1827 » a 1887, a 1820
en 10 » en 100, en 80, en 1
10 de » 12 de, 30 de, 17 de
mao a » mas a
50 de » 30 de, 20 de, 5 de
mar a » mar y
1 50 » 1 20

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 en 10 de mao a 1827 ) OR ( Cabildo abiertas 1 50 de mar a 1850 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta en 10 de mao a 1827 ) OR ( Cabildo abiertas 1 50 de mar a 1850 ))*.
