I have Frankel fron Pruzhany which are tied in with my Faikes family from pruzhany and Brest. All I can say is that sometimes overseas research is costly and there is always a risk that they find nothing. My advice is to do your homework and make sure that whichever archives group you hire that they will be fruitful in their research for you.
