Who Do You Think You Are?, 11.35pm RTÉ One

Christina Applegate made her name with her role in refreshingly anarchic US sitcom Married with Children. In real life, her father, Robert, never knew his mother (or so he thought.)  In what is described as ‘a tear-jerker of an episode’, Christina discovers the painful story of her grandparent's marriage and how it affected her father, who recalled being raised first by his paternal grandmother and later by his father. He also recalled that when he was eight he was told his mother was found dead outside a bar, beaten to death. More than anything, Christina and her father hoped to disprove this terrible story in their arduous investigation of the truth.
