Wow, many of those names are on my list. I started with my Grandma Martha Lowry born Judd and Grandpa Peter J. Lowry and I am working my way up. Martha Judd was the daughter of Michael Judd and Anne Byrne and there were three siblings.
There is a Thomas Judd from Wicklow who was a signal overseer on railway.
On this tree the farthest it goes back is Tonbridge, Brandon Ferry,Bray,, Redcross. I will let you know as I continue to dig. Gonna have fun digging through all your info.
