Perhaps you should try some spelling variations:
"fop peteriv OR peteriv OR petro OR petruo OR petrui OR per OR petrov OR petr o.s.*" » "fop peteriv OR peteriv OR petri OR petruo OR petrui OR per OR petriv OR petr o.s.*" (Expand Search), "fop peteriv OR peteriv OR petru OR petruo OR petrui OR per OR petruv OR petr o.s.*" (Expand Search), "fop peteriv OR peteriv OR petero OR peteruo OR peterui OR per OR peterov OR peter o.s.*" (Expand Search), "fop peteriv OR peteriv OR petrio OR petriuo OR petriui OR per OR petriov OR petri o.s.*" (Expand Search), "fop peteriv OR peteriv OR petruo OR petruuo OR petruui OR per OR petruov OR petru o.s.*" (Expand Search)
