Really depends on the page itself. I don't think all of the pages related to George Washington's family have any business on this wiki, given that they don't have anything to do with the show. But if you can make a reasonable argument for a page to be a direct copy-paste, for instance, it's of such a high quality that rewriting it for a singular wiki would be pointless, then it could be allowed, again, if you cite Wikipedia as a source.
