Who was thaddeus Stevens wife?

Thaddeus Stevens was one of the most powerful men in the US House of Representatives during the Civil War (1861-1865). Considered a 'radical Republican,' he tirelessly worked on behalf of African-American emancipation and political enfranchisement.

Although he never married formally, his common-law wife was Lydia Hamilton Smith, an African-American woman. Their relationship endured for over 23 years, during which time she lived with him as his "housekeeper." At his death he left her a bequest of $5000, a huge sum for 1868.
