you might try the following sites: www.jewishgen.org and yadvashem.org
It is possible that your relatives were from a village in the Podhajce district and not in the town itself? Yizkor books may not list them in that case.
Try to do a search in a wider area ( having been in three different countries between WW1 and 2, Galizia can be a hard place to search in).
Get a person saavy w internet searching if it isnt your thing...you should find something.
Also if Goldfleiss isnt her maiden name maybe you will find her under a different name.
