It was very sad researching Nichlolas and his family. There were so many premature deaths, due to "the consumption".
From what I remember, Catherine's Mother, Hannah Cleary, took Nicholas and the kids in when she died but Nicholas died soon afterwards. I didn't know about Jim, only the girls. It's a shame they were split up but I can imagine it would have been hard for her looking after all three of them.
I've yet to find out what eventually happened to Hannah. Did Mary Ann bring Jim up?
I have Nicholas's father, Daniel, as born in Wexford but it's been a few years since I done the research and it's a bit hazy. I'd love to share our tree with you. I'll pm you.
