Just came across an interesting site, The Irish Famine Project
This site has maps of all the Irish civil parishes and shows you the percentage drop in population in each area.
I subscribe to Irish Central and get inundated with various news related to Ireland. Most I don’t read, but occasionally there is something that is a genealogical gem, like the article on The Irish Famine project. So I persevere with all the rest. Any new developments in Irish genealogy do get reported on this site, so it is worth hanging in there.
This site has an interactive map, so you can look at specific civil parishes and see the decrease in population from 1841 to 1851, due to deaths and immigration. Over a million people died and over a million emigrated during The Great Hunger.
I looked up the population numbers in some of the areas my ancestors came from in Co Tipperary:
Thurles 10,284 pre-Famine and 7,848 after a decrease of 24%
Moyne 2,584 pre and 1,759 after -32%
Drom 2,025 pre and 1,400 after -31%
Moykarky 1,493 pre and 780 after -48%
Loughmore West 2,471 pre and 1,565 after -37%
Fin Dwyer at irishhistorypodcast.ie is doing a series of podcasts on The Famine at the moment. Can’t recommend his podcasts enough. He is a great researcher and his podcasts are interesting and hugely informative.
