Can u tell me how many members in snsd without mother?

Tiffany and Yoona don't , Tiffany's died when she was young and Yoona's abandoned her when she was born , as far as I know , all the other members do. Though Yoona never talks about it , she has a unnie (older sister) though and Tiffany has a brother and sister.

taeyeon & sica the mathers

so teayeon recently added a pic of her mom braiding her hair , yuri mom was brought on a program with sunny and hyoyeon , sunny talked about her mom in hello baby and she put glimpse in it that she is still alive , sooyoung put a pic of her and her mom eating plus she came on a program , hyoyeon said that her mom is the one that brought her to the sment auditions , seohyuns mom came on a program with snsd as a surprise , jessica called her mom once on hello baby and asked her how to make hamburgers , tiffany's mom passed away when she was 11 years old , yoona was abandoned by her mom once she was born and was taken care of by her father and sister but i am not sure if she has more siblings :3
