Per Yurig Francuz interview, 1/13/07: Sperkau was the Yiddish teacher. There was a Sucha, Fela and Surzia.

PER EMAIL FROM SHLOMO SPERKA, 3/16/08: Dear Judy, As you can see my name is Shlomo Sperka. I am fairly certain that the family on your list is my uncle--my father's brother Chaim Szperka. He had three daughters. One Felina or Felia survived an lived here in Oak Park MI. She recently passed away. She lost two younger sisters, Sara Rachel and Fraida Malka, called Franka. Her father was a writer and a "bookish" person, my cousin told me. She didn't mention teaching, but that is consistent . There were familly members in nearby towns. I will be happy to try to provide info if I have it.  I am happy to have found your site. (through a  niece in Israel). Shlomo Sperka
