As proof that DNA is powerful, especially the male line, compare the above sculpture of Henry as a child to the current Prince George, the son of Prince William and Kate Middleton:
I’ll bet George’s cousins will look a bit different.
Except that Prince George, his dad William, grandfather Charles and great grandmother Elizabeth II are of the House of Windsor - previously called Saxe-Coburg and Gotha but changed to Windsor during WWI as to sound less German. Possibly somewhere distantly related to some Tudors but not directly in lineage.
Don't understand why they have Prince Harry's title as Prince of Wales.
