The 'Who do you think you are?' for ordinary folk returns with Derek Mooney at the helm once more. Himself and a bunch of genealogists travel across Ireland to help people explore their family histories. In this first episode, we meet a Lucan lady called Kathryn Murray who wants to find out if she was related to a family in Canada who were massacred by the locals in a blood feud. Because who wouldn't want to know that about their ancestors? Also, a lady called Anne Ryan wants to prove she is related to a Wexford man who fought in the American Civil War and survived Custer's Last Stand.
