Good for you! I am a descendent of William the Conqueror and also Frederick the Great and probably Ghengis Kahn, though that last is not documented.
Now let's do a little experiment. You have two parents, right? And four grandparents. For the sake of argument, let's say there are FOUR generations
per hundred years. It's probably more like five, since women historically were having children at puberty, not some mythical age when society
determined they were "adults,' but I'm opting for some easy math here. And let's start in 2000 AD for the same reason
8-1925 great grandparents
16-1900 great great grandparents
32-1875 great great great grandparents
64-1850 great great great great grandparents
128-1825 great great great great great granparents
256-1800 great great great great great great grandparents
512-1775 (great x 7) grandparents
1024-1750 (great x 8) grandparents; World population: 750,000,000
2048-1725 (great x 9) grandparents
4096-1700 (great x 10) grandparents
let's do every 4th now to make it shorter
65,536 -1600 (great x 14) grandparents; World population: 545 million; Europe: 10 million
1,048,576-1500 (great x 18) World population: 450 million
16,772,216-1400 (great x 22) World population: 350 million
268,435,456-1300 (great x 26) World population: 360 million
4,294,967,296-1200 (great x 30) World population: 360 million
68,719,476,736-1100 (great x 34) World population: 320 million
1,099,511,627,776-1000 (great x 38) World population: 265 million
Note: That last number up there is 1 TRILLION, about 4,000 times the population of the world at that time.
The population statistics are estimates for the entire world. If you are of a certain ethnicity, say largely European, then these figures would be
exponentially less. For example, Europe in 1600 had a population close to 10 million compared to a world population of half a billion. On a worldwide
basis your number of ancestors approaches the population of the entire world by 1300 and far surpasses it, once again exponentially, by 1200 when your
"number of ancestors" at 4 billion compares to a world population of 360 million.
Of course, that didn't happen, did it? The only reasonable explanation is that many, if not most, of your ancestors overlapped so that in real terms,
a person of European ancestry is related to every other person of European ancestry probably from about 1600 or even later on up to the present. By
1500 AD the population of Europe exceeds the number of your ancestors living at that time. Of course, from our perspective today cousins married
cousins. In other words, we're all cousins many times over.
And we're all related to royalty. Your next door neighbor is as much related to French nobility as you are, and is very very likely at least your
20th cousin. It's just that no one wrote down, or he has not yet discovered, the links to take him back there. People did that selectively over time,
of course, concentrating on their "noble" ancestors more than their peasants because they were the only ones written down. So the fact that I am
related to William the Conqueror, and can "prove" it with my charts and graphs doesn't give me much bragging rights when the total number of my
ancestors from 1000 AD is 1 trillion when the population of the entire world was a quarter billion.
