Well... the culture of your ancestors can't do anything for (or against) you in the present day. The so-called Anglo-Saxons were sometimes Anglo, sometimes Saxons, and in many cases neither - e.g., the Normans were a separate culture and a separate people until they invaded and essentially reverse-assimilated. That whole process is very much organic; preserving an identity to specific ancestors long dead, when the culture that defines you has changed, would not be.
