This is splitting hairs somewhat over what "landed gentry" really means. New England was primarily comprised of port cities with mercantile interests and settled by Calvinists with a very different economic structure and work ethic than other states further south. Moreover, the poor soil meant large farming estates were impossible. Sure, there were wealthy people who owned more land than average, but you're mostly thinking of the farm-estates in places like Dover that became the summer and winter escapes for Brahmin families in the 19th century into the present day. But that was all a post-hoc constructed idea of how wealthy people ought to be--owning land in the country and maybe having some farming. So while technically yes, people like the Websters, Saltonstalls, Ameses, and others commanded large tracts of land, they were not really "landed gentry" in the true meaning of deriving their family's main income from agriculture rather than industry, trade, or shipping.
There are reasons whey the Federalists and Jeffersonians clashed and continue to to this day in other forms. The environment, religion, economy, and settlement patterns all were highly different here vs PA and further south.
