Semantics...but I see your point. Basically test-tube grown Astares from pure Primarch DNA as opposed to regular Astartes being made from existing Space Wolves Chapter DNA. Technically, the new Chapters are a kind of Successor Chapter of their respective First Founding Chapters, but not really, since their source gene-seed came from a pure source as opposed to existing Chapter gene-seed with all their idiosyncrasies and genetic drift over millennia.

Definitely like Sons of Russ Chapter idea, but does that mean we should put them in a Space Wolves Successor Category or Sons of Russ Category? What do you think? Oh, and as far as the new Founding go, it's definitely the Ultima Founding and has been referred to as such in all the new sources, though it is technically the 27th Founding even though it has not been referred as such.
