Okay, that's a lot better than I feared.
Since you are the Noble, think hard about a Resources focus - not just the skill, but also Aspects. Being able to *buy* locations in the setting, or found them, is one of the most useful things a vanilla mortal can do: and it isn't hard to ensure a +9 resources roll.
If you make your trouble some variation on Noblesse Oblige then the other PCs will know to bring you into the action, and the GM will be feeding you Fate points.
Anglo-Saxon means you'll be trained to fight on foot, so let one of the commoners be the Survival expert: you only need a point or so to indicate that you can ride and hunt. Instead, have a really high Weapons. Note that you'll be able to afford a high quality war axe, hauberk and shield, so will make an excellent meat shield.
Your Thane may also be a shire reeve (sherrif!) or magistrate, so take a decent Investigate if you want to go this way.
How 'blind' does the GM want your character creation to be? Because OOC it's obvious that having a True Love Aspect etc will be helpful for your PC, some GMs will consider that inappropriate. If the Gm likes the idea of your PCs 'coincidentally' having the tools to defeat the bad guys, consider that if another PC is a weaponsmith, then Aspects such as 'my creations inspire courage/will bring peace to England/are made so that I can afford to wed my True Love/give us hope of defeating the Vikings' will make them very bad news for the local White Court.
