Rabbeinu Yonah (ben Avraham) of Gerondi, France(1200 [or 1180]-1263). The Ramban’s mother and Rabbeinu Yonah’s father were siblings. Many years later, the Ramban’s son, Rav Shlomo, married the daughter of Rabbeinu Yonah. Thus, the two great rishonim were mechutanim as well as first cousins. He was a student of Rav Shlomo ben Avraham Min Ha’Har. When King Louis XIV of France, “Saint” Louis,” burnt all the copies of the Talmud in Paris in the Square of the Louvre, Rabbeinu Yonah, one of the Rambam’s main detractors, felt that the events in Paris were a sign that he and the other opponents of the Rambam were seriously wrong.
