Perhaps you should try some spelling variations:
"fop petriov OR petero OR peterov OR petruo OR peteruo OR per OR petr o.s.*" » "fop peteriov OR petero OR peterov OR peteruo OR peteruo OR per OR peter o.s.*" (Expand Search), "fop petriiov OR petero OR peterov OR petriuo OR peteruo OR per OR petri o.s.*" (Expand Search), "fop petruiov OR petero OR peterov OR petruuo OR peteruo OR per OR petru 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 (petriov OR ((((petero OR peterov) OR (petruo OR peteruo)) OR per) OR petr)) o.s.*.
