I know that Rashi had daughters — either two or three — and no sons. I also know he was a vintner — meaning he made wine. I know he was a student of or student of a student of Rabenu Gershom. I guess I know this all from my schooling. My question is: Where is the source of all this information in classical Judaic sources? Meaning not a recent professor's, or any professor's, thesis, but a source in the rabbinic literature.
