One of the only maps I’ve seen that shows what is a political division, “Dartmouth Parish”, I believe this is a reference to it being a bishopric.
From Coke Upon Littleton: “…the ancient towns called boroughs are the most ancient towns in England; and from these towns come the burgesses of parliament, when the king has summoned his parliament. Every borough incorporate that had a bishop within time of memory, is a city, albeit the bishopric be dissolved…It is not necessary that a city be a county of itself; as Cambridge, Ely, Westminster &c. are cities, but are no counties of themselves, but are part of the counties where they are”
Some interesting features are included, including the Ferryhouse located at the bottom of Old Ferry Road, the flour mill just outside of the town plot, as well as the “three hills above Dartmouth”, (which I believe is in reference to “Mt. Amelia” at the top of Old Ferry Road, “Silver’s Hill” in the Sinclair neighborhood and “Mt. Thom” aka Brightwood).
