Nine-year-old Abraham Lincoln's mother Nancy died in 1818. A year later
his father Thomas Lincoln traveled from the family's cabin in southern
Indiana to their former home in Kentucky, where he married Sarah Bush
Johnston. Sarah became a stepmother to the young Lincoln and his sister.
Sarah encouraged Abraham's attempts to educate himself, although she could
not read or write herself. While the adult Abraham Lincoln did not maintain
a close relationship with his father, he continued to cherish his stepmother
and remembered her fondly.
