Its weird to think that a President who was first elected in 1884, had a child alive in the 1990s, within my own lifetime.

Obligatory mention that President Tyler - who took office in 1841 - has a grandchild who's still alive today.

He's actually older than the oldest living child of a president by 16 years.

Probably Alice Roosevelt (1980) and Naomi Biden (1972).

Naomi dying before Alice must be of even more interest.
