So what I'm asking is this ...
let's take a random ancestor
your great grandmother on your mother's side
did you find out her who her great grandparents were?
To be comprehensive this has to be done with every ancestor so in the end at the very least you should know every grandparent or even better great grandparent's line on both sides of their families
How far did you go back?
I stated how far back I was able to trace in my original post, early 1800's
