I've read a few threads about a surviving Anglo Saxon dynasty post 1066, so I've got two main questions.

Firstly, if Edmund Ironside's older brother Ethelstan had not died in 1014, what changes might originate from that? We know he was supposed to be quite the warrior, and had already won himself quite the reputation. Could the combined might and skill of Ethelstan and Edmund Ironside help prevent the Danish takeover? And keep the House of Wessex more in the long term? If so what might the consequences be?

My second question is regarding Edward the Exile, if he had survived post 1057, was he more likely to have been given East Anglia as an earldom, or Northumbria? And as for the challenges he would face, Harald Hardrada and Sweyn of Denmark seem likely, would William Duke of Normandy invade as well for a shot of glory?
