Silent Witness actress Liz Carr discovered explosive links to South Armagh as she delved into her family tree.
The leading disabled rights campaigner, from Birkenhead, was tracing her roots on Who Do You Think You Are? on BBC1 when the mission brought her to Killeavey, Dromintee and Armagh.
She soon found out that her great-great-great-grandfather Bernard 'Barney' Ryan was implicated in a plot to assassinate a wealthy landowner.
He was presented as a leading figure in the Ribbonmen, a secretive Catholic society which came together to take action against landlords and their agents in the 19th Century.
Despite being severely wounded from multiple shots fired from a ditch near Dromintee, Meredith Chambre survived and an associate of Ryan's, Frances Berry, was executed in Armagh Gaol over the plot.
For Carr, it was confirmation of family folklore that a relation had been involved in an altercation in Co Armagh - but she admitted the reality was something she "could never have imagined".
Watch as details of her family's history in Armagh are relayed to Liz Carr:
She said: "My cousin in Canada said that one of my relatives was involved in an assault or an altercation. So I went to Northern Ireland and it was like a treasure trail.
"I was blindsided by a history I could never have imagined. Barney was from a working class background so it’s rare that there’s a lot of documentation. But I was able to touch something with his writing on.
“I don’t approve of how far it went but I don’t feel ashamed of Barney. The reason the men involved were fighting for change and justice, I understood.
"It’s about vengeance against a greedy, malicious landowner. That radicalism sits comfortably with me.”
Carr's episode brought the curtain down on the latest series of Who Do You Think You Are?, marking a milestone in the process.
And Carr told What's On TV: “It’s the one show where I’d say to my agent, ‘Could you tell them I’d really like to do it?!’ It’s astonishing that I get the honour of being the 150th person. I’m very lucky!”
