Well there is a very cool website online that is recognized by the national geographic.
It cost money for the DNA kit. They send it to you, you swab your cheek and send it back.
You can then log in and you can see anyone else that is in your DNA string, so to speak.
The only problem with that right now is, not everyone in the world is a member. Some
day I suspect, if not that website, another, will have everyone in a DNA database so that
everyone can match up to their ancestors.
I think it gets very confusing after going back several generations because so many things
change. Take me for example. I am adopted. However I know who my parents are but
IF someone was to look up my birth certificate, the original is locked, even to me, and all
they would get is my grandparents names as my parents. So there is the adoption factor.
Also, people get married and divorced and remarried, and some marry and divorce multiple
times.....to top that off, they have children often from more than one marriage. People tend
to follow the paternal side since that is the name that carries onward but just as much is to
be taken into the history on the maternal side.
I agree, any way you look at it, we are all related.
