Looking for information on the surname Apfelbaum and afiliated family

My grandfather left Poland as WW2 broke out and i wanted to know if there was any information out there about his family and there life there.

Thanks
Leah

There may be information about him on some of the Jewish ancestry websites which, I have found, are quite comprehensive.
EDIT: Aside from the better-known sites, Brigham Young University (Utah) has an extended database of searchable records.

Thanks for that what sites have you used?..He is From Tarnow if anyone has any information on that town that would be great to.

thanks

My grandmother's maiden name was Apfelbaum her name was Pauline Apfelbaum, she was from Brody Galicia / Austria. Her fathers name was Leigh or Leibish Apfelbaum

Brody is now in Ukraine - it was however within Polish territory during the Interbellum (i.e between the Ist and 2nd World War)
