Perhaps you should try some spelling variations:
abierto en » abierta en, abierto y
100 del » 1900 del, 10 del, 1990 del
en 100 » en 10, en 500
c 1860 » c 1870, a 1860, j 1860
r 1857 » r 1856
mar c » mar a, mar y
15 de » 1 de, 12 de, 17 de
mar r » mar a, mar y

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 100 del mar c 1860 ) OR ( Cabildo abierta de 15 de mar r 1857 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto en 100 del mar c 1860 ) OR ( Cabildo abierta de 15 de mar r 1857 ))*.
