What additional information are you trying to find, as you know dates of birth? What religion were the family? There may be baptisms in church records which may give parents for your grandmother & great aunt.
Tell us what resources you have tried - you say you have had no success with The Stadt. Is that where Polish events were registered & certificates issued? I cannot find them on familysearch.org.
You may have more success on the 'Europe' board on rootschat where a Polish expert may read your post [your post title does not specify where so you could change that as well using the 'Modify' button at the top right of your first post; a moderator can move your post to a more appropriate board - click on the 'Report to moderator' button at bottom right of your post and request it is moved.
