Deletion of Benjamin Warrington

Comment: He's mentioned in a number of histories of Nauvoo and the events surrounding the death of Joseph Smith, as I summarized in https://en.wikipedia.org/w/index.php?title=Benjamin_Warrington&type=revision&diff=867800596&oldid=867758761 expanding the article slightly. No coverage is in-depth, but it's borderline when combined per . The key question for me is whether https://www.josephsmithpapers.org/person/benjamin-warrington this source, a biographical entry in the digital edition of the https://www.josephsmithpapers.org/articles/about-the-project Joseph Smith Papers project, is a reliable secondary source; if it is, Warrington is notable, because it gives substantial coverage about his birth, career, and death based on what seems to be carefully compiled primary sources (censuses, local archives, etc). The project says it's been endorsed by the National Archives’ National Historical Publications and Records Commission, which sounds impressive
