There were not nearly that many Jute holdings compared to Saxon and Angle ones. The only Jute kingdoms were Middlesex, Kent, and on the Isle of Wight, and those are all under Wessex or East Anglia domain by the time of the game.

Again, I'm limited here on what I can do simply by renaming.

The Jutes were massively significant in Britain. Anglo-saxon is just a term for all of the English tribes. It also means the Jutes, as they were just a important as the Angles and Saxons.

Well there's a limit to what I can do, but also the Jutes that never left have largely been assimilated in with the Danish and those that did leave for the isles are largely assimilate in with the Saxons and maybe some Angles.
Jutes were never that significant in Britannia and stopped being all that relevant in Denmark around this time.

Jutes?
