It does appear that memory is returning, though, but probably as members of the Northern Kindom, not of a specific tribe therein, would be my guess.
That could well be true. Some scholars place a great deal of emphasis on intra-tribal cohesion during the migrations westward and northward, to the point of citing Biblical and other evidence they feel links certain tribes to certain current countries.
Unlike the basic Lost Tribes of Israel history outlined at my Profile, I have never felt entirely comfortable making those associations.
