WikiTree discuss "Kindred Britain" via wikidata

As WikiTree has WikiTree person ID (P2949) and use Wikidata to suggest changes they have started a discussion about Kindred Britain and the quality

Kindred Britain FAQs state:
In common with many scholars of works about culture or history, the compiler of Kindred Britain made a conscious decision not to include references for the sake of retaining broad accessibility and legibility. This is a good faith effort made by an individual trained as a scholar. Mistakes have undoubtedly been made: in an exploratory effort of this kind, there can be no illusion of perfection. On the other hand, without exploration, there can be no possibility of extended knowledge or understanding.

another comment

that the data has been scraped into Wikidata and thus it will propagate into WikiTrees's Suggestions/DBEs system. There is no quality control in WikiData, hence the rubbish scraped in from The Peerage.
