Thomas "Tad" Lincoln
"Tad" Lincoln was the youngest of President Lincoln's four sons, and was
named after his grandfather, Thomas Lincoln. Tad was very much a prankster at
the White House, as his parents were unwilling to discipline him after the
death of Willie. He outlived his father by only a few years, dying of a
respiratory illness in Chicago at the age of eighteen.
Only one of Lincoln's children survived to adulthood; Robert Todd Lincoln,
who was present at his father's death, and went on to have a distinguished
career as United States Ambassador, and was buried at Arlington National Cemetery.
