Tiana's Goddess Wheel
The Wicker Morgans of Avalon
The Morgans of Avalon are nine sisters who control the weather in Avalon/Glastonbury, have special powers and represent the changing stages of life. There is not a great deal written about them thus far that I have found, but we can make our own interpretations. To me, they appear to be nature spirits associated with the rolling hills, running streams, and gardens of Glastonbury. They are the local wheel for Glastonbury, just as the wheel of Britannia is the larger reaching wheel of Britain. They represent nature as it appears specifically in Glastonbury; however, they also represent Avalon and can appear at Avalonian portals all over the world. Glastonbury's close connection to Avalon means it appears to have adopted the Morgans as its local spirits.
The Banners of our Wheel
There is overlap between all three wheels. Britannia's Domnu, Avalon's Gliten, and our Môr are all feminine aquamarine energies of the sea, rivers and rain; they all hold seals, fish and dolphins sacred; their colour is blue; the rule of emotions, freedom and the stage of womanhood between the lover and pregnant mother. There are going to be similar because nature and the seasons around Britain are very similar. There are not identical all over though: compare the landscape of Mid-Wales to that of South-East England for example.
And so, after our discussion we decided that, as suggested above, the later two wheels are localised. These nature spirits are a part of the larger Goddess - Gliten's energy (Glastonbury's water) is a part of Domnu's energy (All water in Britain). Gliten may be called a Morgan, or even a nature spirit and not necessarily a Goddess perhaps due to a measure of cult importance or how we perceive 'Goddess'. To some, a Goddess i vast and would rule over a whole land rather than just a comparatively small town, or even just a river; however, if the local spirit of a lake began to receive a cult their importance could be raised to our definition of a Goddess - like Morgan Le Fey perhaps?

It lies in our definition. The Anglo-Saxon's did not appear to distinguish between a God or a Nature Spirit early on. Furthermore, I see The Goddess as the primordial force in all of nature, so whether Goddess, nature spirit, demi-goddess or priestess, all are Her. They're all just as big and important really.
To summarise then, I'd say the Wheel of Brittania could be called all around Britain. You could also, or instead, call the wheel of your local landscape which brings these national Goddesses to your location. To complicate things ever so slightly, one may suggest the Morgans can be called anywhere also, as they are linked to Avalon - the Otherworld - which has portals all over the world.
A big thank you to Amie for the thealogical discussion! )O(
