I was messing around online and found out a very fitting and cool name for a Chapter descended from the Blood Angels:
Cado Angelus (Fallen Angels)
This would be a perfect fit for Sanguinius' heirs. The it single-handedly tells of a tragic and sad story to some of the most noble of warriors, those who fall to the Black Rage.
Hello new chapter...
