Hart v. Fanny Ann
In Montgomery County, KY, the 1803 will of William Hart granted freedom to his slaves when they turned 30-years old, along with all of their children, should they have any.
The slaves freed by Hart's will were Alsy, Lucy, Anna, Selina, and Turner. Lucy turned 30 in 1825 when her daughter Fanny Ann was 10 years old. William Hart's heir interpreted the will to mean that Lucy was free, but Fanny Ann would not be free until she turned 30. Fanny Ann filed suit in the Montgomery Circuit Court and was granted her freedom in accordance with the terms of William Hart's will.
Hart's heir appealed the decision to the Court of Appeals of Kentucky, where the lower court's judgment was affirmed with costs on October 22, 1827. The point of contingency in the case was the word "with" and whether it denoted connection to. The courts were asked to determine whether, when a slave is promised freedom, the slave's children also should be freed at the same time.
