Marcus Agrippa appears to be either Phasaelus the "elder brother" of Herod the Great or the son of Phasaelus also called Phasaelus.
Certainly Marcus Agrippa was no commoner as Roman history currently assumes. We have already seen that Herod was likely either the son of Mark Antony or Publius Clodius.
We can expect much the same for Marcus Agrippa. This topic deserves more study, as does the name Agrippa itself.
I'm now thinking that the name Agrippa is a Latin variation on Grypos "hook nose", as in Antiochus VIII Grypos.
"Latin and Greek names for a griffin is 'gryps' which is taken from the Greek "grypos," meaning "hooked," and refers to the hooked beak of a griffin."

1205, from O.Fr. grifon "a bird of prey," also "fabulous bird of Gk. mythology" (with head and wings of an eagle, body and hind quarters of a lion, believed to inhabit Scythia and guard its gold), from L.L. gryphus, misspelling of grypus, variant of gryps (gen. grypos), from Gk. gryps (gen. grypos) "curved, hook-nosed," in reference to its beak. But Klein suggests a Sem. source, "through the medium of the Hittites," and cites Heb. kerubh "a winged angel," Akkad. karibu, epithet of the bull-colossus (see cherub).
