Well, I know that there is speculation in the lore that when the two expunged legions were disbanded, the Ultramarines saw an unprecidented surge in numbers. It isn't too far of a stretch to say that some loyalists from the traitor legions were folded into other legions, but having a chapter directly descended from the traitors might be a bit much.
The Blood Ravens are rumoured to be descended from the Thousand Sons, but I think that came from fan speculation, and GW just kind of shrugged and say what ever.
Personally, I have a hard time getting behind the idea that there are chapters that are from traitor genestock. The legions were broken down to chapters after the heresy when Guilliman finalized the codex. It just doesn't strike me as likely that they would keep the traitors geneseed around to risk it being stolen, let along put it into active marines for fear of the same thing.
