History Photographed on Instagram: "President John Tyler, born in 1790, has two living grandsons as of 2018. ⁠ ⁠ The 10th U.S. president’s continued lineage is due to Tyler having children late in life, and one of his sons also having children at an advanced age. ⁠ ⁠ This unusual generational span means three generations of the Tyler family have lived across most of American history, from the 18th century into the 21st.⁠ ⁠ Credit: @cbseveningnews"
