No a known bloodline is where you know the people from their line ie. Finn=Sage and Troy. We don;t know who Kol sired or who was apart of Kol's bloodline so therefore it is unknown
No it isn;t because they all have a bloodline we need to know the people they have sired to make it a known bloodline because otherwise we might as well put Rebekah, Elijah and Mikeal on there to. Unless you have the name or names of Kol's bloodline the bloodline is still unknown.
They all have a bloodline that was estblihsed in the episodes but Kol only has a mentioned bloodline not a known one. There is a difference.
We don't know who Kol turned just that he has a bloodline. For it to be known though we need to know who he turned or who was sired from the people he turned.
It was just reference but Elijah and Rebekah both have killed and turned people but it;s not about that. Kol's bloodline is still unknow either way and I'm changing it unless you can give me the names of people Kol turned like Finn and Klaus have.
Having a known bloodline is having that we know exist. Klaus, Finn, and Kol have one that we know that exist. It has never been said the other Originals have a bloodline.
