Closest living Lincoln descendant

[LincolnToddFan]

I know that actor Tom Hanks is a Lincoln descendant through the matrilineal line, but my understanding is that AL's last direct descendant died in December 1985. (Robert Lincoln Beckwith, great grandson)

It's rather sad but maybe it's for the best. AL's grandchildren had no interest at all in their famous ancestor and seemed a spoiled, feckless lot. The late president's "good genes" apparently died with his own offspring.

Who knows what disgrace and embarrassment future generations would have brought to his legendary name.
