British Israelism
British Israelism (also called Anglo-Israelism) is  the hypothesis that people of Northern European descent, particularly those in Great Britain, are the direct lineal descendants of the Ten Lost Tribes of Israel. The doctrine often includes the tenet that the British Royal Family is directly descended from the line of King David. 
      2 Kings 17:18 states that after losing to King Shalmanezer thousands of the northern ten tribes of Israel fled to Judah. Those who did not escape the Assyrian armies, were deported to Assyrian territory in 722 B.C.  The most likely area is in current Armenia  After this time, mention of the ten northern tribes (Israel) is rare in Scripture.
     Is it believed that many of these deported Israelites escaped captivity and travelled westward through Europe after the fall of the Assyrian Empire to Babylon - no doubt escaping during the political confusion that ensued.  We can guess at the route they took by the names they gave to the rivers, mountains and cities as they travelled northeast - the Danube River and dozens of mountains, streams and towns bearing the names, Din, Dan, Dun, or Dyn—named after the tribe of: Dan..  When they reached Germany the went northward and settled in Dan's Mark - Denmark  From there they spread out into the Low Countries and Northern France. From Breton and Brittany in France they migrated to England.
     The tribes of Israel get to England and fulfill God’s promise to Abraham: by ultimately calling their promised land Great Britain. "In Isaac thy seed shall be called 'Great'" (Genesis 21:12)

     They had always called themselves Britain, Briton, or Breton. The word Britain is pure Hebrew for Covenant Land,  and British, means man of the covenant in Hebrew.

     The Sovereigns of Great Britain are crowned in King Edward’s chair, so called because it was commissioned in 1296 by King Edward I to contain the coronation stone of Scotland — known as the Stone of Scone — which he had captured from the Scots who had kept it at Scone Abbey. Some Scottish legends surrounding the stone have identified it with the Stone of Jacob (Genesis 28:10-22). It is believed the Stone of Jacob was brought to Ireland by the prophet Jeremiah about 600 BC. Then it ended up in Scotland as the result of the Irish immigration beginning in 400 AD.

     The Stone of Jacob appears in the Book of Genesis as the stone used as a pillow by the Israelite patriarch Jacob at the place later called Bethel. It was there that Jacob had a vision in his sleep in which God promised him that his seed would "bless all the families of the Earth". He then consecrated the stone to God. It is mentioned as part of the coronation ceremony of the kings of Israel where it is called "a pillar".The  musical instrument called a Pipe in the Bible is actually a bagpipe, noted for its mournful, droning sound..And Joseph’s “coat of many colors” was actually the family tartan—a plaid (i.e. many colors.)

      There are ancient drawings showing the Jewish royalty wearing plaid kilts.prior to 600 BC.
