Wins court case to regain son. Three important events took place in Isabella's life over the next two years. She found refuge with Maria and Isaac Van Wagenen, who bought her from Dumont and gave her freedom. She then underwent a religious experience, claiming from that point on she could talk directly to God. Lastly, she sued to retrieve her son Peter, who had been sold illegally to a plantation owner in Alabama. In 1828, with the help of a lawyer, Isabella became the first black woman to take a white man to court and win.
