Hello Mr. Cornwell,
i read your Saxony Story and i like it very much.
Now i read a book about the Hanse, in which it is explained how it cames to different town names for the same town at the same time in Germany.
A settlement of merchants/traders is named with -wig (wik/wyk/wiek…)at the end if its placed beside/outside of a castle=Burg or stand alone. The castle/fortress is named -burg.
In the case of London then: Lundenwig and Lundenburg/-ceaster(in latin) at the same time. Also Brunswig, later Braunschweig, or Schleswig, Bardowick.
Perhaps you already knew it. A answer is not necessary ;) I am waiting eagerly for the next book about Uhtred in german language.
Yours faithfully
Joachim Tiede
