After reading both books I would say that a lot of the stuff on the Black Legions 40k Wiki entry isn't correct anymore, exspecialy seeing them as simple Sons of Horus successors.

you oculd say the same about the death guard and ho they take in many plague marines from other chapters, etc... or the red corsairs are not the successors of huron's old chapter, etc....
as for the rest, make a list of things you want taken in and talk to the wiki staff about it.
