From Lady Anne Blunt’s “A Pilgrimage to Najd” (1881): “To the present day in the North, the Anazeh distinguish the descendants of the mares brought with them from Nejd as “Nejdi” while they call the descendants of the mares captured from the tribes of the North, “Shimali” or Northerners.” and: “The Anazeh have disappeared from Nejd. They began to move northwards about two hundred years ago, and have ever since continued moving by successive migrations till all have abandoned their original homes. It may ben that the great name which Nejd horses undoubtedly have in the East, was due mainly to these very Anazeh, with whose horses they are now contrasted.” I had noted these two passages in comments on an earlier thread from 2019, but I thought they were worth bringing back.
