All Sontarans are descended from the Kaveetch, and the non-clone purebloods from a pre-Rutan War colony surely have more in common with the original Kaveetch than the clones. So I don't see why they wouldn't be mentioned in their respective articles.

While merging the articles altogether might have been premature, there is no contradiction in the story itself, so it's obvious that the Purebloods are descendants of a group of Kaveetch that established a colony before the War.
