The way I have read her up bringing is her oldest brother was in a coma close to when she was born, he was in hospital/medical center? very close to their home. He lived for like 6 years then died. To me it was the first years of her life that she probably didn’t get much attention.
Looks like to me that after his death her father then made up for it.
I have wondered if her father somehow hooked up with JE and invested the money he stole from his businesses. Her father was buried on the mount of olives, there have been articles about her father being Mossad. It was not long after she goes to NY and meets JE. She got 80000? Month from father and JE took care of her.

To be fair he had enough money to buy the Ghislaine which cost a lot
