It would save a lot of time and energy if you would actually read my post all the way through.
Please note that I said,
Many of them have no dates, no sources, and sometimes not even full names listed. (Emphasis added.)
So I already stated (although perhaps not expllicitly enough) that before adding any profiles for people listed in ThePeerage.com, I would expect that people would find other sources (preferably primary sources, although the farther back in time you go, the harder those are to find) for those people.
I do think Darryl's a good guy, and I consider ThePeerage to be an extremely ambitious project, especially considering that he's doing it all himself. But he's only human, and just as prone to mistakes as any of us. (Show me a source with "no errors" in it, and I'll show you a source that hasn't been checked thoroughly enough. I write in to Library and Archives Canada, the B.C. Archives, FreeBMD, and Find A Grave to note errors often enough that they probably groan, "Oh, no. Him again!" when they see my address in the From: line, and my fingerprints are all over certain articles on Trove and Wikipedia.) I have sent him any number of corrections on the basis of sources that I have turned up for the profiles that I have worked on. But I also recognise that he hasn't finished transcribing all of Burke's Peerage yet, let alone processing all the corrections he's been getting by email. (Some of which appear to be inaccurate, due to people passing on family lore which isn't verified by sources.)
So I don't consider ThePeerage.com a primary source, and always list links to it beneath a "See also:" header when I add them. (And, similarly, I don't consider Wikipedia to be a primary source, either, and link to it the same way.)
All that being said, we can't just write off ThePeerage.com. The people running Wikidata have decided to add all the entries from ThePeerage.com to Wikidata, sourced or not. Since Aleš's suggestions include data from Wikidata, including possible family members, and a lot of those connections come from ThePeerage.com entries, Wikitreers are already seeing suggestions based on the contents of ThePeerage.com. Therefore, it seems to me that the wise thing to do is research ThePeerage.com entries properly, and have the correct information already on WikiTree, so that if anyone goes to add a profile on the basis of an entry on ThePeerage.com, they'll see that:
- It's already been done, and
- it's been done correctly,
and therefore not add incorrect information to WikiTree.
I would also argue that it's also in our interest to pass on the corrections we turn up to Darryl, so that he can correct the errors on ThePeerage.com, so that it will no longer have incorrect information on it. (Granted, in my experience, it usually takes him about three weeks to make a correction, and that process would probably take even longer if more WikiTreers sent him corrections. But that's just one of the costs of fighting for goodness, niceness, and the accurate way. And other sites can take months to make corrections.)
