איסי בר היני

Ishi bar Heini ascended from Babylon during the time of Rav in the presence of Rabbi Yochanan, and Ulla happened to come to his house [Shabbat (157a) and he asked him, and in Chulin (137b) Rabbi Yochanan said to him, "What is the difference between you and me" (there)? And for no reason did they write the genealogies of Ishi bar Heini].
