Around 1844 she married a free black named John Tubman and took his last name. (She was born Araminta Ross; she later changed her first name to Harriet, after her mother.) In 1849, in fear that she, along with the other slaves on the plantation, was to be sold, Tubman resolved to run away. She set out one night on foot. With some assistance from a friendly white woman, Tubman was on her way. She followed the North Star by night, making her way to Pennsylvania and soon after to Philadelphia, where she found work and saved her money. The following year she returned to Maryland and escorted her sister and her sister’s two children to freedom. She made the dangerous trip back to the South soon after to rescue her brother and two other men. On her third return, she went after her husband, only to find he had taken another wife. Undeterred, she found other slaves seeking freedom and escorted them to the North.
