Perhaps you should try some spelling variations:
"fop peterov OR petruov OR petruov OR petriv OR petrv OR petro OR petr o.s.*" » "fop peterov OR petruov OR petruov OR petriv OR petrv OR petrov OR petr o.s.*" (Expand Search), "fop peterov OR petruov OR petruov OR petriv OR petrv OR petri OR petr o.s.*" (Expand Search), "fop peterov OR petruov OR petruov OR petriv OR petrv OR petru OR petr o.s.*" (Expand Search), "fop peterov OR peteruov OR peteruov OR peteriv OR peterv OR petero OR peter o.s.*" (Expand Search), "fop peterov OR petriuov OR petriuov OR petriiv OR petriv OR petrio OR petri o.s.*" (Expand Search), "fop peterov OR petruuov OR petruuov OR petruiv OR petruv OR petruo OR petru o.s.*" (Expand Search)
