Apologies for my absence- I'm going to rework the current House Tyrell CS to have a comprehensive family tree, as well as explain better the History of the Reach, as well as a few other things I'd like to go over. 

Also, I'd like to clarify- I've specified named characters from the Reach too, in terms of Houses. The Footlys (Owain), Hightower-Tyrells (Loras), the Peakes (Paxter), and the Redwynes (Arthur) are all pretty much named houses and/or people. This is as well as naming the Goldengroves, Oakhearts, and I think the more minor house of Stanton. I think that's pretty much it for the Reach- if you're going to use any other characters from the past Houses of the Reach (the Florents are no longer a House in the Reach, for example, neither are the Hightowers, as they've merged with the Tyrells), I can also pad that out.

EDIT- the beginning of my CS has been revamped. Take a look- it looks nice now :)
