We should here carefully distinguish this word from word number 1 because they are quite similar names.
We have this name in Neh 12:13, last word in the verse. It means Yahweh has been (or was) gracious, Yahweh had compassion.
There is also a more simple form: יוֹחָנָן, with the same meaning (look at 1Ch 3:15)
Pronunciation: y(e)hoHanan. In its more simple form: yoHanan.
