Birth and early life

Rashi was an only child born at Troyes, Champagne, in northern France. His mother's brother was Simeon bar Isaac, rabbi of Mainz. Simon was a disciple of Gershom ben Judah, who died that same year. On his father's side, Rashi has been claimed to be a 33rd-generation descendant of Johanan HaSandlar, who was a fourth-generation descendant of Gamaliel, who was reputedly descended from the Davidic line. In his voluminous writings, Rashi himself made no such claim at all. The main early rabbinical source about his ancestry, Responsum No. 29 by Solomon Luria, makes no such claim either.
