[Verginius Rufus]

Lyon Gardiner Tyler, Sr., lived until 1935. He was President of the College of William and Mary for many years. His younger sister Pearl Tyler was born in 1860 and was thus a year or two old when former President Tyler died--she lived until 1947.

Between my grandfather's grandfather's birth and my grandfather's own death was a span of 197 years--not quite the record of Tyler's grandchildren. My grandfather had a younger sister who outlived him by 4 years--she died 201 years after her grandfather's birth.

From John Tyler's birth in 1790 to his last child's death in 1947 is 157 years.

From my great-grandfather's birth in 1835 to his last child's death in 1981 is 146 years. A shorter span but not by much.
