Perhaps you should try some spelling variations:
"fop petriiov OR peterov OR peteruiov OR petruio OR petriuuio OR petr o.s.*" » "fop petrov OR peterov OR peteruiov OR petruio OR petriuuio OR petr o.s.*" (Expand Search), "fop peteriiov OR peterov OR peteruiov OR peteruio OR peteriuuio OR peter o.s.*" (Expand Search), "fop petriiiov OR peterov OR peteruiov OR petriuio OR petriiuuio OR petri o.s.*" (Expand Search), "fop petruiiov OR peterov OR peteruiov OR petruuio OR petruiuuio 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 ((petriiov OR (peterov OR peteruiov)) OR ((petruio OR petriuuio) OR petr)) o.s.*.
