Does anyone else here have a family story about Jewish British roots?

My father’s side of the family has a story that his paternal line is remotely descended from Jews, who were kicked out of England a long time ago, when there was a king who kicked out all the Jews. According to the story, most of the Jews who got kicked out of England went to different places in Europe, such as France, but some of them just went a little north, and basically went into hiding for generations in, of all places, Scotland. Then (goes the story) one day there was a star of Russia, who was looking all over Europe for skilled workers to build up his empire, and that’s how our family got to Eastern Europe and connected/reconnected with other Jews somehow. And then we were therefore generations, mostly working as builders for by the Tsar because we had been builders in Scotland, until Grandpsa came to America. (Note: I know this whole thing sounds ridiculous, and I am not saying it is true, I’m just saying that it’s the story that not saying this is true, I’m just saying that this is what Dad and Grandpa told us, and at some of our cousins got told the same story too when they were young. Dad said that he was told this by Grandpa, and Grandpa said that he was told this by Great-Grandpa (who died long before I was born because the Nazis killed him in Rivne in 1937 ), so I don’t know how far back the story goes before that, but we were told it had been passed on from father to son basically forever. Some of my family totally believe this, or at least they really want to believe this, some of my family just believe it is totally a ridiculous family myth with no possible basis, and I am undecided because I have found some tantalizing suggestions and hints during research but nothing firm.(Also, a complication is that great grandpa was an orphan adopted in childhood, who adopted who took the family name of the people who adopted him. He had had a different family name before, but the family name that was passed down to us is the one that is supposed to have been the family name that came from our family having it a long time ago before we came to Eastern Europe, whenever that was.) Parentheses

Does anyone else here have some kind of family story like this, about roots from what would have been the 1290 expulsion of England’s Jews? If it’s just some cute family myth with no basis, I can live with that (although I know that a lot of my relatives would find it very hard to live with).
