Nelson was descendant of Edward III and of Brian Boru.
Louis XVI, King of France, was descendant of Charles I and of Brian Boru.
Marie Antoinette was descendant of James I and of Brian Boru.


If no Brian Boru, then Louis XVI, Marie Antoinette, Wellington and Nelson could not exist. French Revolution and Napoleonic wars entirely different.



Archduke Franz Ferdinand, descendant of James I and of Brian Boru.
George V was descendant of Brian Boru.
Kaiser William II was descendant of Victoria and of Brian Boru.

The Yalta conference in WW2.
Winston Churchill, descendant of Henry VII and of Brian Boru.
Franklin D. Roosevelt, descendant of Edward III and of Brian Boru.
(Haven't got Stalin yet!)

Garret Mor Fitzgerald, Garret Og Fitzgerald and Silken Thomas also all descend from Edward I and from Brian Boru.

Is there a theory of amazing descents?
There is.




Trying to estimate Most Recent Common Ancestor (MRCA) of all living humans.



First, consider studies in genetics.
Based on inheriting DNA.


Easiest to track are:
  1. Female-female ... line only. ("Mitochondrial Eve") (Just 1 of your billions of lines)
  2. Male-male ... line only. ("Y-chromosomal Adam") (Just 1 of your billions of lines)
MRCA for both is in pre-history - maybe 100,000 to 200,000 years ago.




Nature paper in 2004.
Most Recent Common Ancestor (MRCA) of all humans in any line.





Charlemagne, Holy Roman Emperor (born 742 AD).


Computer simulations say:


Computer simulations say:
Brian Boru is probably ancestor of everyone in Ireland today. (Except recent immigrants.)




We all descend from Brian Boru.
But can you prove it? (Step by step)
Ryan Tubridy can.
My wife can. (She has the House of York descent too.)


In 2020 I finally proved it for myself.
