Although it's been a few years back when I spoke with William Nolan in Dublin he was a professor at Trinity College in the Geography department at the time. I, like many others, am certain the information on my great-grandfather's immigration from Castlecomer is contained in that list of individuals. I would love to be able to afford the time to get into the archives and transcribe all that information for those of us who need to utilize it.
However, Tom Lyng, of Kilkenny City, wrote a very good book entitled "Castlecomer Connections" which I purchased from him. I spent an interesting afternoon and evening with him and his wife while in Kilkenny. He was born and raised in Castlecomer and extremely knowledgable about the history of the area. He was an aged man when I was there but very clear of mind. In the back of his book are some pages of Famine Emigrations 1847 to 1853 from the Castlecomer area. It is broken down by townlands and gives the name of the immigrant and how many went with him or her. I am more than willing to see if the individual or individuals you are looking for might happen to appear on these lists if you don't have the book. Unfortunately it doesn't give any other data, but it's a start. Let me know.
