Adolf's father is uncertian, however, it is probable that Adolf is a grandson of Fabian-Feibusch Gassmann and I have created a placeholder for his father to create this link. A tree on geni.com shows his father as Loebel Jehuda Gassmann.

Isaac and his wife could each be the conflation of two siblings.

Fabian's name and marriage to a Nothmann strongly suggests that Ascher is a grandson of Fabian-Feibusch Gassmann.



According to Joachim's 1877 marriage certificate, Ascher was deceased and his last residence was in Himmelwitz, while Joachim's mother, named as Emilie Jettel Gassmann geb. Prager was living in Zabrze.
