e marcelo » de marcelo, y marcelo, de marcel
marcelo a » marcelo c, marcelo _, marcelo e
abierta a » abierta y, abierta de, abierta en
a 1820 » a 1920, a 1850, a 1827
mar de » mar del
ana c » ana m
a 12 » al 12, _ 12, a 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 abierto ana c e marcelo a 1820 ) OR ( Cabildo abierta a 12 de mar de 1880 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto ana c e marcelo a 1820 ) OR ( Cabildo abierta a 12 de mar de 1880 ))*.
