zaeed himself narrates the blue suns founding on his loyalty mission. the del'serah connection is a result of a writing bungle for game plot and codex entries. the bit that says vido is "not" head of the blue suns can be seen here. note: "co"-executive officer, not "chief". and the bit about vido ceding leadership to dal'serah... here.

it's like the codex entries are the in-universe equivalent of wikipedia: not everything there is reliable.

however, we can presume that jona sederis is the overall eclipse boss because supporting material said so (codex) and because no other material ingame and out states otherwise. the other bosses can be considered flunkies because enough datapoints on merc leadership are there (again, codex and related 'notable members' section on each of the merc entries).

the issue concerning blood pack origins... i think i've also got it figured out (warning: speculation).
 * 1) blood pack is a small vorcha gang.
 * 2) ganar wrang transforms blood pack into what it is today
 * 3) since wrang was exiled, obviously he cannot/did not want to return to his own tribe (GANAR). so he probably joined up with WEYRLOC and became a chief there.
 * 4) profit
 * 1) profit
