Here is a website that lists sites to do with the Great Hunger that have been identified all over Ireland. It is a site that is interactive and interesting to use. Just paste the link into your browser and give it a try by clicking on any of the locations. Look for the town or city where your family came from or places you are planning to visit.
Neil Whelan, creator of the website, has been in touch with Marie Smith regarding his wish to set up a Great Hunger directory. As you will see, this is a work in progress and Neil is updating it as he gathers information. You may be able to supply input in this regard. The website projects a very clever concept and it is obvious that some serious work has gone into it.
