Dick Eastman weighed in the other day with his commentary about the Obama-Cheney linkage. Yesterday, I spoke briefly with Alex Cohen of NPR and tossed in my two cents' worth. What I tried to explain is that we all have millions of distant cousins, so there's a good chance that there are a few famous ones in the mix. The trick is plucking them out from the millions -- especially if you're a true genealogist and actually verify every single link!
