Royal biographer claims King Charles III and Trump share common ancestor

Across the long corridors of genealogy, where bloodlines blur and centuries compress into footnotes, a royal biographer has suggested that King Charles III and Donald Trump share a common ancestor — a claim that has rippled through Brazilian media and drawn from Trump a joke about Buckingham Palace. Whether the connection is historically grounded or merely the latest in a long tradition of speculative kinship, it touches something perennial in the human imagination: the desire to find hidden threads binding the powerful to one another.
