Got back to about 1500 for sure, and with a leap of faith (there's a gap) back to 1066. It's nailed back to Jamestown about 1620. After that you
really can't be sure. On the other side I have it to about 1803.
You really have to take anything past the census tapes (1790 was the first) with a grain of salt. Records just weren't that good. People made stuff
up. It's fairly easy to find a "line" that plugs into someone famous where more work is likely to be done. I got back to 1620 because I found a
book published in 1885, a genealogy of the Montague family that had my great great grandmother in it. People have been working on the Montague
genealogy for several hundred years.
But think through this. There's a generation every 25 years or so on average, four generations per century. If you go back a mere 1,000 years, to
approximately 1,000 AD (close enough to 1066 in my example above), that's two to the 40th power. Your number of ancestors? 1,099,511,627,776. The
world population estimates for 1000 AD vary, but are around 275 million.
1. There has been a lot of overlap.
2. You are related to nearly everyone who lived in 1000 AD, including Kings & Queens.
3. We're cousins.
Why are you related to everyone who lived in 1000 AD? because all it takes is one guy, one Marco Polo to go to China and have offspring, one Dr.
Livingstone to father children in Africa. Those people's genes flow throughout the population in time. So someone from China has just a little bit of
Western European DNA, and vica versa.
So at a certain point genealogy becomes meaningless. Even if I try to go back to 1620 and Jamestown, that's two to the 32nd power, which is over 4
billion ancestors in just 400 years.
