But I'm a Saxon!
Now if I could only figure out which branch sallied forth to the new world I could lay my rightful claim to the family crest, coat of arms and of course hereditary lands. Alas.
If all else fails, I could just get a boat, assemble a clan of naturally violent fellows and retake said lands in the historical tradition of my migrating ancestors!
Slaughter, rapine , plunder, pillage (burning of sacred places) etc etc all the traditional folkways! our homely customs are all lost. You may have to gruesomely murder any surviving male heirs to your fiefdom and enslave their womenfolk, do you feel lucky?
