On February 1, 1850, Eddie Lincoln died of "consumption," probably tuberculosis, after a fifty-two day illness. A funeral service was held in the Lincolns' parlor the following day. Several days later an anonymously submitted poetic tribute titled "Little Eddie" appeared in the Illinois Daily Journal. Many believe it was written by Abraham Lincoln.
The sadness at the loss of Eddie must have been lessened somewhat with the arrival of Lincoln's third son, William Wallace, on December 21, 1850. The family greeted their fourth son, Thomas (Tad) on April 4, 1853.
