I have the same question as the original poster, Steven. I have pretty much found the people I am interested in, but would now need a good professional researcher to find some deeds, wills etc. to tie up some loose ends, which are most likely available in Dublin. I have not the time and know-how to visit Dublin and find my way around in the various archives.
KGarrad, can you PM me with the info about the researcher you used?
