Perhaps you should try some spelling variations:
"fop peterov OR petruv OR petro OR petrii OR peteri OR petr OR petru o.s.*" » "fop peterov OR petruv OR petrov OR petrii OR peteri OR petr OR petru o.s.*" (Expand Search), "fop peterov OR petruv OR petri OR petrii OR peteri OR petr OR petru o.s.*" (Expand Search), "fop peterov OR pentruv OR petro OR petrii OR peteri OR petr OR pentru o.s.*" (Expand Search), "fop peterov OR petriv OR petro OR petrii OR peteri OR petr OR petri o.s.*" (Expand Search)

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

• Removing quotes may allow a broader search: fop ((peterov OR petruv) OR ((petro OR (petrii OR peteri)) OR (petr OR petru))) o.s.*.
