Season two of "Who Do You Think You Are?" has come to an end, but last week's episode was a true treat to watch. The episode explored Ashley Judd's ancestors, who accomplished some truly amazing feats.

First she explores the life of her third great grandfather Elijah Hensley, a man who at the age of 15 enlisted to fight as an infantry member of the Union Army in the Civil War. Elijah was imprisoned twice by the Confederates, and ultimately lost his leg in a battlefield amputation before his honorable discharge in 1865. Ashley was touched to learn about Elijah's harrowing story, and his bravery in the face of adversity.

Next Ashley investigated her great grandfather William Dalton, whose death record led her to discover her relation to one of the founders of this nation, William Brewster. Brewster was born in the mid-16th century and was a notable member of the Puritan movement in England. Brewster immigrated to the U.S. on the historic journey of the Mayflower in 1620.

Ashley was touched to learn about these two ancestors who had led such extraordinary lives. The journey helped to inform her passion for social justice, and strong principles, which have long been part of her family's legacy.
