There was a Chana Falka Zinger (Singer) Jaffe (Joffe) who was the daughter of Yoel Zinger (Joel Singer), but she was the wife of Rabbi Mordecai ben Moshe Joffe of Krakow as documented in numerous scholarly sources including the Jewish Encyclopedia. The dates and children given in the profile are also incorrect. One of her children was Rabbi Kalonymos Joffe of Lublin. "Margaliot" should not be in the name. The "half sister" listed has many problems including inconsistency of dates.
