Last night's 'Who Do You Think You Are? on BBC1 featuring Brendan O'Carroll took on a more unusual format. The star and creator of the hit comedy show 'Mrs Brown's Boys' had requested the programme to specifically look into the history of his grandfather Peter O'Carroll and his tragic murder in Dublin in 1920. The programme was able to assist Brendan in his search to find the perpetrator of the murder nearly one hundred years ago. Discovering the fact that his family was under surveillance by the security services we find how law and order was administered under British rule at the time. Brendan's grandfather was murdered by a particularly ruthless intelligence officer, Major Jocelyn Lee Hardy in his quest to find out the whereabouts of Peter's sons, known IRA supporters. What did you think of last night's show, did you prefer the format of just looking at one ancestor or do you prefer the more usual 'Who Do You Think You Are? 'style? Let us know.
