Andrew Jackson was president of the United States from 1829 to 1837. Previously he commanded American forces in the 1812 Creek War against the 'Red Stick' Creek Native Americans, running "the Creeks up the creek", as Scout puts it. The Finchs' ancestor Simon Finch moved to Alabama as a result of this war.
