so, here’s a question

i wonder to whom i am related. i’ve done a fair amount of genealogical research, and i have a database with a few thousand people to whom i am related in some way or another… and there’s this piece of information, which i figured out when i was just starting out, about 15 years ago:

1             – self
2             – parents – 1 generation ≅ 25 years
4             – grandparents – 2 generations ≅ 50 years
8             – great grandparents           – 3 generations ≅ 75 years
16          – 2x great grandparents    – 4 generations ≅ 100 years
32          – 3x great grandparents    – 5 generations ≅ 125 years
64          – 4x great grandparents    – 6 generations ≅ 150 years
128       – 5x great grandparents    – 7 generations ≅ 175 years
256       – 6x great grandparents    – 8 generations ≅ 200 years
512       – 7x great grandparents    – 9 generations ≅ 225 years
1024    – 8x great grandparents    – 10 generations ≅ 250 years
2048    – 9x great grandparents    – 11 generations ≅ 275 years
4096    – 10x great grandparents – 12 generations ≅ 300 years
8192    – 11x great grandparents – 13 generations ≅ 325 years
16384 – 12x great grandparents – 14 generations ≅ 350 years
32768 – 13x great grandparents – 15 generations ≅ 375 years
65536 – 14x great grandparents – 16 generations ≅ 400 years

according to the research i have done, i’ve traced one thread of my family fabric back to the 1620s, but i’ve only tracked 11 generations, which indicates to me that there was a shorter time between generations, the further back you go, but it’s an accurate number of relatives, even if the number of years isn’t exactly accurate…

but, i think about 65,536 people who had an active part in my creation, despite the fact that they never knew who i am, and probably never knew anybody other than the people two or three generations to either side of them… and i also think about the approximately 7,000,000,000 individuals that currently inhabit the planet, all of whom have the same 65,536 relatives, some of whom are the same people… and 65,536 only goes into 7,000,000,000 approximately 106,812 times…

so the probability is pretty high that you, and i, and everyone else, are related to pretty much everybody, if you go back far enough…
