Can we draw the following hypothesis from the context?

Context:

Eli ben Yehudah ha Nazir ben Zechariah, Arabic Abu Kathir Yahya al Katib ("Father of Kathir, Yahya the Scribe" fl.Tiberias, 910s) was a grammarian and philologist of the Hebrew, Arabic and Aramaic languages. He may have been among the teachers in Tiberias of Saadia.

Hypothesis: Eli ben had a long name
It's impossible to say
