Hate to tell you this, but those folks were no more Anglo-Saxon than the Pope, and he's Polish! They were Norman, more French that English, and many of them didn't even speak the same language as the people they ruled. They spoke French at home and took French wives, and considered their property in France to be much more important than their property in England. It was certainly more valuable.
But, we have news on now - something about a hijacking attempt thwarted at Dulles airport - much more current than Hindus being killed over 700 years ago!
In actual fact they were originally from Denmark. They were "vikings." They conquered northern France, started speaking French, then conquered England. No doubt along the way they intermarried with French and English.
By the time of William the Conquerer, the conquered English were, racially--Anglo-Saxon-Jute-Frisien, Nordic, Celtic. The conquered French were Germanic (Franks were a German tribe), Celtic. For what this is all worth.
