-Secondly why in god name is Harold's dynasty called the "of Wessex"'s. Is this a temporarily place-holder because as his name shows Harold Godwinson was from the House of Godwin. The House of Godwin (Godwinsons) and House of Leofric (Leofricsons) were the most powerful Saxon houses at the time of William's conquest. Why not portray this?
In CKII, patronymics are shown separately, and we avoid using them as dynasty names whenever possible. The full name of Harold, which can be seen in-game, is Harold Godwinson of Wessex. The regnal number is wrong because there are currently no kings prior to Harold scripted in the history files.
