What makes The Ancestral Dictionary a reliable source? The author says the data in it was "partly furnished by other persons". Genealogical data is infamous for its inaccuracies; I know nothing against this particular book, but I don't see a publisher which makes me think this is self-published.
I looked up the Law Intelligencer in Mott's history of American magazines and have a little more information for you: "The Law Intelligencer, founded at Providence in [1829], was, after a single volume, [...] moved to Philadelphia, where it published a second and third volume, 1830-1831." There's a footnote that adds 'It added the words "and Review" to its title when it was moved to Philadelphia. The titles given are those of the half titles and captions; title-pages say United States Law and Intelligencer Review.' From this it's apparent Angell continued to edit it in Philadelphia.
@Mike Christie: Hi! So I researched about this last week in the Google books], Internet archive, and other online sources. From what I saw and read, it is indeed apparent that he continued editing it, so I've just rephrased and added a bit. Didn't add about "and Review", as it is not too related to Angell. Does it work? – Kavyansh.Singh (talk) 13:34, 2 September 2022 (UTC)[reply]
