The grandson of the 10th US President has just died

John Tyler was born in 1790 – 235 years ago. He became the 10th President of the United States, yet his grandson has just died.

He had 15 children between 1815 (when he was 25) and 1860 (when he was 70). He was President from 1841 to 1845.

One of the 150 was Lyon Tyler who was born in 1853 (when John was 63) and lived until 1935. He had six children including Harrison Tyler who was born in 1928 (when Lyon was 75!) and Harrison died on 25 May 2025, aged 96.

So by having children at age 63 and then age 75 and then living to be 96, you have the grandson of the 10th US President alive until 2025.
