Wow, that's quite a lineage. I had to search and search just to find ONE gggg uncle who served in the Civil War (Union). I guess I must come from a long line of draft dodgers. LOL.
Then, too, we forget that these people had friends, cousins, and so forth, and if we can find them, we can sometimes find our own ancestor, particularly since there were many fewer people in the country 150 years ago.
As an example, one of my GGGrandfather's took pioneers West. He belonged to a peculiar church. Bill Clinton's GGGrandfather also took pioneers West. Billzo's own father belonged to that same peculiar church. So, did they know each other, work together, live in the same towns, etc?
Working backwards through Billzo's family (Blythe) it's theoretically possible to find out where my own GGGrandfather lived and what he did. (NOTE: I have more information on Billzo's family than he does because we had to do exactly that.)
Interestingly enough, his (my GGGrandfather) only son became a business partner of R. Emmett Tyrrell, Jr.'s Great Grandfather.
Small doggone world if you ask me ~ and it only took us 50 some years to find those little nuggets.
