Yisro (Jethro) יתרו

Yisro was the priest of Midian. Moshe fled from Egypt to Midian and married Yisro's daughter Tzipporah (Shemos 2:15–21).

After the Exodus Yisro heard of the miracles and came to the desert, saying 'Now I know that Hashem is greater than all gods' (18:11). He saw Moshe judging the people from morning to night and advised appointing officers over thousands and hundreds (18:13–26). The parsha of Matan Torah bears his name. Rashi brings that he had seven names (Rashi Shemos 18:1).
