Perhaps you should try some spelling variations:
pedrod » pedro, pedros, pedron
pero » pedro, peru
perozo » pedrozo, peruzo
merodo » merodio, morodo, merono
herode » herodes, heroe, herod
ceron » aceron
cero » acero
pro » prof
{acute}active » {acute}activa

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((pedrod or pero) or ((merodo or herode) or perozo)) or (ceron OR cero)) or pro){acute}active ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((pedrod OR pero) OR ((merodo OR herode) OR perozo)) OR (ceron OR cero)) OR pro){acute}active ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((pedrod or pero) or ((merodo or herode) or perozo)) or (ceron OR cero)) or pro){acute}active ;".
• Adding a wildcard symbol may retrieve word variants: ((((pedrod or pero) or ((merodo or herode) or perozo)) or (ceron OR cero)) or pro){acute}active ;*.
