Yochanan Lowen is researching is ancestor Mamche Feingold whose grave says she is the daughter of Yehuda Leib, a descendant of Rebbe Elimelech Lipman (Weisblum) of Lizhensk Maybe someone can help him establish the connection. I thought maybe his Yehuda Leib might possibly be the same as Rabbi Arye Leib David Lebovics but Yochanan says Mamche's father was not a rabbi.
