Hmm, so what kind of Duchy names would you get? I'm always terrible at any kind of naming, so I'm left wondering how our current Duchies could be renamed.
My own duchy has been named "Duchy of the First Temple" for historical reasons.
I could easily imagine duchies such as "Duchy of West [realm]", "Duchy of the Isles" or "Ducal March", depending on geography.
I am certain people will come up with even better names. However, most probably city names will always remain popular.
