The point of the programme is for people to find out about their ancestors.
Those who have stopped watching missed something incredibly interesting to do with this country and how it treated the Irish at the beginning of the last century. Yes, it could have been in a differnt sort of programme, but it wasn't. It was about O'Carroll's grandfather. What I found very brave of him was the amount of information he found out himself just by looking at newspapers. This is an area of genealogy that is sometimes overlooked.
I am sure we all know bits about Irish history and the IRA. To find out that Michael Collins was mentioned in the reports is interesting.
If it had not been for O'Carroll worrying away at what he knew, he would never have found out what really happened to his grandfather.
Surely that's what this series is really about. He was visibly upset when he found out that the man who shot his grandfather had been unpunished, as any of us would have been, I hope.
