It is interesting to note further global impacts of the Norman and Saxon migrations in history.
For example...when the bormans conquered England many of the noble Saxons fled to transylvania. (Odd choice but they did). Vlad the impaler came from Saxon ancestry. Transylvania is sort of the Yankees of Romania.
Sicily, meanwhile, was also conquered by the normans. And much of the unique cultural differences between Sicily and mainland Italy are the result of Norman rule. Sicily is the southerners of Italy.
