Clooney is the half-first cousin five times removed from Lincoln, meaning that two of their ancestors were half-siblings.
This means that Lincoln's mother Nancy Hanks was the half-sister of Clooney's fourth great-grandmother Mary Ann Sparrow.
Hanks and Sparrow shared the same mother, Lucy Hanks, but had different fathers.
Lucy Hanks was Lincoln's maternal grandmother as well as the fifth great-grandmother of Clooney.
