Hello.
I know, it's been over two years, since you have posted this message, but if you are still interested in obtaining some information on your Bem familiy members by a chance, I could help. Both Waksmund and Lopuszna villages are very close each other and I'm familiar with this area, so it's not a problem for me to go there and conduct some research.
In case of any additional question, you can also reach me at

Regards,
Michael
