ר' אושעיא

Rabbi Oshaya bar Chiya, Rabbi Oshaya bar Rabbi, and Rabbi Chiya bar Rabbi, all together [(Yevamot 46b, as explained by Rashi)]. He taught it, and he said to her that the halacha is in accordance with Rabbi Nathan; Rashi explains that the Mishnah differs from his teacher, and he said to her from his own understanding. [(Chulin 31a) This one brought the genealogies, and there is only Rabbi Oshaya the younger from Chaveria].
