> Yet the paucity of yhwh names.

Many of the biblical names ending in "ah" are YHWH names. This includes many of the prophets. So Elijah, Zechariah, Jeremiah, Micaiah, Isaiah, for instance are all "ah" ending names that have a meaning related to YHWH in the same way that the "el" ending names are related to El. And then Joshua (and, hence, Jesus) is also a YHWH name.
