The last living grandson of the 10th U.S. President John Tyler has died at 96 years old — the end of a link to a bygone era of American history.

The cause of Tyler’s death on Sunday was not immediately released. John Tyler was 63 years old when Harrison Tyler’s father, Lyon Gardiner Tyler Sr., was born. And Harrison Ruffin Tyler was born in 1928 when that father was 75 years old and the presidential grandfather had been dead for more than 60 years.

He was the last of three generations spanning nearly the entire history of the United States: When his grandfather was born, George Washington had just become president.
