Lincoln was an affectionate husband and father of four sons, though his work regularly kept him away from home. The oldest, Robert Todd Lincoln, was born in 1843 and was the only child to live to maturity. Edward Baker Lincoln (Eddie), born in 1846, died February 1, 1850, probably of tuberculosis. Lincoln's third son, "Willie" Lincoln was born on December 21, 1850, and died of a fever at the White House on February 20, 1862.
