Photo Received from Reva Rudolph, Nov 1998 and identified as follows:
Front Row: Rivka Flax, oldest sister, Yitzchak Flax, father
Back Row: Neshel (Nettie) Flax, Nochum, her hsuband, Adel Flax, youngest sister.

My family info prior to this, from Uriel Flax showed Nettie with three husbands, none of whom were “Nochum.” This guy looks very yourn to be her husband. Is it possible he is actually Yitzchak’s only son, Louis David (Uncle Laibel?)
