@christineburns @zoe Evn if it didn't work out as hoped, I hope that there is some reward in having filed a gap in your family tree. It's good to know where you come from.
I too have ancestry from down that way, mostly on the Wicklow side of the county border, where my Hugenot ancestors did well for a few centuries, in a strong farmer way. Sounds like Janes Byrne had a tougher deal, but maybe you & Olga can enact one of my favourite songs, and Follow Him Up to Carlow https://youtu.be/tvECtlJQ4dU
