I'm not sure this will help, but we may have a connection somewhere along the line.
My Paternal great grand mother's name was Helen (Yehudit) Teiksler born 1858, and her ship manifest from 1906 indicates that she was from Stanislawow. She had 2 sons, Abraham and Israel, and Abraham had a son Moishe.
Helen was married to Samuel Benjamin Zweifler in Stanislawow, but since it was a religious one, not civil, it was not sanctioned by the Austro-Hungarian government, and she, Abraham, Israel and Moishe all retained the Teiksler name.
When Abraham married, his marriage certificate confirms the above names. However, it also indicates that Helen's parents were Hersh Tzvi Schwartz and Miriam Kessler.
Just on the basis of similar names, does any of this ring a bell to you ...may we possibly be distant cousins?
By the way, I have run into similar problems with the lack of available records in Galicia.
I'd appreciate you getting back to me one way or another ... thanks!
