PRINCESS JULIA GRANT CANTACUZENE - A further example of how families migrate is the story of Julia Grant, granddaughter of President Ulysses S. Grant. She married Prince Michael Cantacuzene, who was descended from the rulers of the Byzantine Empire during the later centuries of its existence. Afterwards, the Cantacuzene's moved north and became noblemen of Russia under the Tsar. In 1899 shortly before she married, she met William Lyon Mackenzie King, the future Prime Minister of Canada, and carried on a correspondence with him until his death, sharing a common interest in spiritualism and efforts to contact the dead. She died in 1975.
