Nancy Hanks Lincoln was the mother of U.S. President Abraham Lincoln. Her marriage to Thomas Lincoln also produced a daughter, Sarah, and a son, Thomas Jr. When Nancy and Thomas had been married for just over 10 years, the family moved from Kentucky to western Perry County, Indiana, in 1816. When Spencer County was formed in 1818, the Lincoln Homestead lay within its current boundaries. Nancy Lincoln died from milk sickness or consumption in 1818 at the Little Pigeon Creek Community in Spencer County when Abraham was nine years old.
