Hinda Minka Zwiebel

I have started a family research project and am seeking some long lost cousins of my great grandmother Hinda Minka (Lieberman) Zwiebel - who was the only survivor amongst her parents and siblings.
Her mother's name was Doba Shpringer (born 1876 from what I heard in Woźniczna, Poland & married Alexander Zusha Lieberman born in Sanz, Poland in 1880). It is told that Doba had a brother who had a son named Chatzkel (Yechezkel) Shpringer that survived the war came to Israel with his wife Hilda as refugees via Shanghai in 1949/50, and after a short period of time immigrated to the United States, and that's the last my family has heard of them.
I'd be more then grateful if anyone can assist me tracking down this family in the United States, or suggest where I may be able to find more information.
(I have searched some databases but haven't found any relevant information).
Thank you dearly,
Joseph

Hi everyone,
I am searching for info about my great grandmother who apparantly was the only survivor of her family - the rest as per family rumor were killed in Auschwitz.
Her name was Hinda Minka Lieberman (Zwiebel). Her parents were Alexander Zusha & Doba Lieberman.
When she was 7 years old, she fled with her family from Poland to Hanover, Germany. In around 1930 she married my great grandfather Tzvi Yakkov Rosen Zwiebel and they moved to Berlin. In 1933 they fled Germany and went to Israel.
(The name of the place she came from is something like Ushpizon, but I'm not certain about it)
Hinda Minka passed away in 1988. The family rumor is that after the war a distant cousin had provided testimony that all her 10 siblings were killed. Hence on her gravestone a general mention of her family is made.
Would anyone be able to try help me find out more details about her family, and exactly when and where they were killed?(I'd be very intruged to find out more about her extended family, perhaps some relatives that survived can be found?).
I am attaching her gravestone, which reads almost anything we know about her.
(I have found that her mother Doba Liberman was born in Wisnicz, Poland in 1876. She was a housewife and married to Aleksander. Prior to WWII she lived in Hannover, Germany. During the war she was in Bonzin, Poland).
Any help would be greatly appreciated.
