Take a moment or two to absorb that. John Tyler, our tenth chief executive, was born in 1790, when George Washington still had nine years to live, John Adams and Thomas Jefferson, 36 years each. The Tyler who now lives in the family home is neither President Tyler’s great-great grandson nor his great-grandson but his grandson. In the person of Harrison Tyler, in other words, we Americans are still only a couple of generations removed from the men who founded this Republic. [Link]As Randy points out, Harrison is the result of two randy old men fathering children: President Tyler at age 63, and his son Lyon Gardiner Tyler at age 75. My paternal grandfather would be 96 were he alive today. Harrison's would be nearly 217.
