This reminds me of hearing about President Tyler who knew some of the founding fathers yet has a grandson alive today or he just recently died, i think.President Tyler had 19 kids and the youngest was born when he was much older... it is amazing how not that long ago some of these things were.Just seems like way back because of all the advances in technology,etc.
President Tyler still had two living grandsons as of January 2012. Lyon Tyler, Jr and Harrison Tyler.
