Eliza was the daughter of Sarah Phillips and John McCardle, a shoemaker. Fortunately she had received a good basic education which she shared with her new husband. He already knew his letters and could read a bit, so she taught him writing and arithmetic. With their limited means, her skill at keeping a house and bringing up a family -- five children in all -- had much to do with Andrew Johnson's success. He rose rapidly, serving in the state and national legislatures and as governor. Like him, when the Civil War came, people of east Tennessee remained loyal to the Union; Lincoln sent him to Nashville as military governor in 1862. Rebel forces caught Eliza at home with part of the family. Quite aside from the tragedy of Lincoln's death, she found little pleasure in her husband's position as President. At the White House she settled into a second-floor room that became the centre of activities for a large family: her two sons, her widowed daughter Mary Stover and her children; her older daughter Martha with her husband, Senator David T Patterson, and their children. As a schoolgirl Martha had often been the Polks' guest at the mansion; now she took up its social duties.She was a competent, unpretentious, and gracious hostess even during the impeachment crisis. At the end of Johnson's term, Eliza returned with relief to her home in Tennessee, restored from wartime vandalism. She lived to see the legislature of her state vindicate her husband's career by electing him to the Senate in 1875, and survived him by nearly six months, dying at the Patterson's home in 1876.
