for years, if you read old posts,I have looked for the four siblings of my GF, John Patrick Neligan, born Ballinvounig,1870,arrived and settled in Bangor, Maine. I had hoped for more cousins, but alas, now that http://labs.familysearch.org has Irish Records up to 1958, I had a researcher get me the death certs of all four sibs........none married, but at least I know now, what happened to them all. So, first cousin's of my GF, are the closest I can gather, so the search will never end.
