The Maharam Asch - Ungvar and Descendants

I am doing research on my late mother's family. She was born in Ungvar in 1925 to Menachem and Bleema Weiss and both of whom perished in the Holocaust. Menachem is a descendant of the Sapinka family and Bleema stems from either Rabbi David or Rabbi Menachem Asch. Rabbi David Asch served in Sobrance and become Rabbi of Ungvar after Rabbi Menachem Asch passed away. Any information or leads that can shared would be sincerly appreciated.
