When President Barack Obama was born in 1961, President Herbert Hoover was still alive. When President Hoover was born in 1874, President Andrew Johnson was still alive. When President Johnson was born in 1808, President John Adams—the second President and one of the original revolutionaries—was still alive.
So the U.S. is only 4 Presidents old.
The Washington Post created this chart to illustrate when Presidential lives overlapped. George Washington and James Buchanan lived at the same time. So do George. H.W. Bush and the late William Howard Taft.

Two grandsons of President Tyler (b.1790) are still alive. It's conceivable that there are people alive with a grandfather born before 1776.
