Toldos Yesh"u is a medevil polemical Hebrew text or related texts that describe a story of Yesh"u ha Notsri. It is not cerain when first written but scholars guess anywhere from 500 to 1000 CE. I want to know if this text was read on Nittel Nacht.
The tradition of not studying Torah or Mishneh on Nittel is well established:
Chasam Sofer 7:31; Makor Chaim of Chavos Yair 155; So was the custom of many Jewish communities including: Rav Yonason Eibashitz, Rav Yaakov Emden that so is custom of all Geonim, Rav Yisrael Salanter, Maharsha, Maharam Schick and others. See Nitei Gavriel Chanukah p. 385
Because Toldos is NOT Torah or Mishneh Torah or anything passed from the sages one assumes it ok to be read and indeed I suspect it seemed fitting at that time of the year. But I want to know for sure if this is a real minhag. To me it seems like no Torah study on Nittel is a real Minhag and reading Toldos came in response. But please prove to me this is a real custom or was. All I can find are Christian source quoted here http://thetorah.com/nittel-nacht-an-inverted-christmas-with-toledot-yeshu/
"A similar description appears about half a century earlier in the writings of Johannes Pfefferkorn (1469-1523), and a few decades later, in those of Julius Conrad Otto (1562-1607) and Samuel Friederich Brentz (converted in 1601), all Jewish converts to Christianity. All three cases add that on Christmas Eve, Jews were accustomed to publically relate the story of Jesus, that is to say, they read the popular Jewish narrative Toledot Yeshu (“Life of Jesus”), also familiar as Ma‘aseh Toleh (“The Tale of the Hanged One”).
Former Jews attacking Judaism are the ones supplying this info, so I think it should be questioned.

There is one Jewish author which theorizes in perhaps what is only only a suggestion: "Sarit Kattan Gribetz suggests that Toledot Yeshu was cast in the same literary mold as the Scroll of Esther, and like it, was publicly read on particular occasions, such as Purim and Christmas Eve."
