Yes,
@Vatterholm himself posted a map here earlier as well. Here you have his concrete suggestions:

While the map above is too detailed for it to be adopted as the province map of the area (otherwise each area would have to get a similar amount of provinces and performance would suffer too much) we can always use it to reevaluate the Norwegian province and duchy setup together with what Vatterholm posted.
It is often difficult to find basis for duchies, and the names are usually just important centres rather than the names which would have been used at the time given the lack of sources and of political unification. If we use the thing names, they duke names would also be adapted as you get into below.
i would not use things as basis for duchies. considering the larger ones are mainly an effect of centralization during the early 2nd milenium.
i also made
a rough map sketch based on more or less same sources as Vatterholm. what i consider a basic subdivision is divided by red borders and numbered in black, the most priority additions in red and further possible divisions in grey.
this is a suggestion for the early medieval/viking era.
i suggested duchies based on more or less traditional regions.
Viken (austr and vestr)
mentioned many times in
Morkinskinna/
Fagerskinna. mainly austr i vikr or simply vikr.
during early medieval era this area is generaly consider to stretch from
Gøta elv,
Kungælv/
Kunghella.
viken literally translates to the fold, as in a folded piece of cloth, and this is the modern norwegian designation of the area subdivided in Østfold and Vestfold.
during early 2nd milenium the area around Gothenburg/Gøta elv was a Norwegian region called
Elfarsysla.
elv being modern scandinavian for river is quite possibly the basis for the region of Alfheim, rather than the supernatural alv(elf), located roughly between the rivers Glomma and Gøta.
on the western side of the fold/vik is located the kaupang at
Skiringsal, that along with
Borre would constitute the center of a powerful petty kingdom.
Telemark at this point (early medieval) is generally considered to be the elevated inland area, separate from Grenland/Vestmar at the coast. upper Telemark could be considered an oppland (scarcely populated, unaccessible wilderness/border area).
this area likely under some kind of Danish control during early medieval era.
quite possibly the supposed Norwegian branch of the Ynglings were initially backed by Danish kings.
Oppland
centered around modern Oppland and Hedemark this is elevated and inland area. yet a geography of wide valleys, flats and good farmable land gave room for a substantiable population. also the area is the location of lake
Mjøsa which through the river
Vorma drains into
Glomma.
being landlocked, the decentralized valley landscape and with only secondary access to trade, this area would likely be subservient to and liable to taxation/tribute by the realms in Viken.
along with Råbygjalag (upper Agder) and (upper) Telemark this area would likely be free of direct danish influence, decentralized and autonomous.
Sud-vest Riki
the south-west realm, mainly Agder and Jæren, Rogaland and Hordaland.
the relatively flat and mild climate of Agder and Jæren show clear signs of large scale animal husbandry during the late roman era. the scale such that it suggest some sort of cooperative effort and the produce, in form of wool/cloth, exported to the continent and Britain. the settlement at
Landa in
Forsand (1500bc. - 600ad.) is norways oldest town-like settlement.
the Norse were well aware of Britain and the continent in general. yet before the use of sail became common the safest route, rather than risk rowing in open sea, would be to follow land eastwards and cross over to Denmark before heading west. this benefited the kaupangs along the route and supported local magnates.
it seem that it was by the same coastal route that bronze once came northwards, from the Baltic, which would make the strait between modern Sweden and Denmark an important economic and strategic location for a long time. this would be part of a trade route originating in the
White sea and ultimately joining the Amber route.
this northern route, especially the ability to control travel sheltered inside the skerries along Norway, which gave rise to local magnates/petty kings at locations such as
Avaldsnes at
Karmøy.
when the use of sail became common, allowing a quick and easy crossing, it opened up a direct link to Britain and the continent. this must have disrupted trade in the kaupangs of eastern Norway and could be one reason for Harald Fairhairs forceful unification of Norway. certainly this area composed the last unified stand against Harald at
Hafrsfjord.
Mærr
Møre and Romsdal, Sogn and Fjordane.
an area comprised of long and steep fjords, the location of several petty kingdoms, also here Harald Fairhair fought a lot of people.
the name Møre/Mær is also found
in Sweden and is thought to point to ocean-landscape, possibly from latin mare. at some point in medieval era north Møre was located in outer parts at the mouth of
Trondheims fjord.
Trøndelag
the wide and relative flat landscape gave room for a sizeable population and Trøndelag composed a counter-weight to Viken throughout medieval era.
by the time of Harald Fairhair Trøndelag was ruled by the
Jarls of Lade. this family seem to have originated in
Hålogaland and could claim a
prestigeous ancestry comparable to the Ynglings. it was certainly by support from this dynasty that Fairhair could claim Norway.
controlling the northern part of the trade route Trøndelag would also extract the
Finn-tax, that is monopoly on trade with exotic furs, antlers and walrus-tooth by Sami.
