Genealogy / Adopted from Poland; trying to find my biological parents [99]

I found this thread trying to help my cousin find her birth parents. Her & her sisters were adopted in Poland by an American couple. Would someone be able to point us in the right direction? She has been trying for years with no luck. She has her birth mothers full name & birthdate as well as a former address. As far as her birth father, she has only his name. As I understand, Poland has strict privacy laws so it is difficult for us to do this on our own. Any searching she has done in the past has been a dead end. She really need some answers...or closure. Thank you for any guidance!
