If you follow his male-line paternal ancestry, his sixth great-grandfather was Prince Karl Anton August (born 1727, died 1759) of the dukedom of Schleswig-Holstein-Sonderburg-Beck.
However, if you follow the lineage of the British monarchy, another of his sixth great-grandfathers was King George III (1738-1820) of the house of Hanover.

Everyone knows that "Prince" is a family name that goes back four generations in his mother's family. His grandfather, great-grandfather and great-great-grandfather were all named "Prince Screws." His grandfather had two daughters, Kattie and Hattie, therefore, there were no boys to pass the name on and the name skipped one generation. The spelling of Katherine's last name was changed to "Scruse" when the family moved North. When Michael had male children, he carried on the family name in honor of his mother.
