What mark did the Normans leave in Jewish culture?

We are talking about the period from the VIII to the XI century, the contribution was as follows:

Mythology and Literature. The Normans left behind the sagas, the cult of the gods Odin and Thor and the epic Beowulf.
State building. The Normans created the duchy of Normandy in the north of France and were noted in the Balkans, Sicily, in the Byzantine Empire and in Ancient Russia (from Rurik to Yaroslav the Wise).
Architecture. For example, in Dublin, they erected a castle and also Trim Castle can be attributed to the Norman heritage.
Language. Icelandic and Faroese began to develop from the western dialect of their language.
