There was a Spanish bishop in the 15th century who, because of criticism of his conversos ancestry compiled a genealogical history of all the noble houses of, I think, Aragon. His conclusion showed that even then there was not a single noble house that did not have at least some converso blood. Even Torquemada had converso ancestors. Indeed, on the arms of my grandmother's mother's family who are from Spain there is an unusual device, a yellow (actually gold) fess (horizontal bar) charged with three 6 pointed molets (they look like Stars of David) and are also yellow. It's unusual because almost never do you see one metal charged on top of another, and even rarer the same metal, in this case gold atop gold. It's almost as if it was not meant to be noticed.
As mentioned in Calvin and Hobbes,
"Would you let in a dog that wasn't housebroken?"
The Hatfields and the Abdullahs, I call 'em.
NO cheers, unfortunately.
Here is another clue...
The Lion is on the crest of many houses of Europe.
It is normally red.
It is the symbol of the Lion of Judah, of the House of David.
It seems lots of nobility trace their lineage back to King David.
