abierta et » abierta en, abiertas en, abierta de
5 mario » 3 mario, 6 mario, a mario
mario e » mario de, mario a
13 de » 1 de, 12 de, 17 de
mar a » mar y
al 5 » al 15, al e, al v
e 10 » de 10, en 10, 8 10
1 13 » 1 1, 1 15, 1 3

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 et al 5 mario e 10 ) OR ( Cabildo abiertas 1 13 de mar a 1850 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta et al 5 mario e 10 ) OR ( Cabildo abiertas 1 13 de mar a 1850 ))*.
