Lincoln's Children:
In 1843, the couple had their first son, Robert Todd Lincoln. Three years later, in 1846, they had their second son, Edward Baker "Eddie" Lincoln. However, when Eddie was only 4 years old, he died of what is thought to be tuberculosis. Their third son was born in 1850, but died of a fever when he was 12. Thomas Lincoln was born in 1853, but he died of heart failure at the age of 18. The only child to live until adulthood was Robert, whose grandson was Robert Todd Lincoln Beckwith. Robert Todd Lincoln Beckwith was Abraham Lincoln's last descendant and he died in 1985.
