Is this for a map of Poland?

I think it is split into two fields.  The first part increases
sequentially for names with the same stem but different prefixes and
the second part increases sequentially for each different suffix. I am
less sure about the suffix part.

I was hoping that I wouldn't need to implement this, but I can see if
the prefix part makes a difference if I can get a test running.
