Andrew Johnson (1808-1875)

He was preceded in the Presidency by Abraham Lincoln, stepping in after Lincoln was assassinated. He served one term in office for the Republican Party and was succeeded in 1869 by Ulysses S. Grant. Having originally been Lincoln's Vice-President, he served his term without one. He is famous as the first President to be impeached in office, and has gone down in history as one of the worst Presidents. He and his wife were the parents of five children all of whom lived to adulthood.
