Jillie, I too find this a very sad thread. My hubby and I have just returned from our second 2 week tour of Ireland. First time visting Wicklow, Wexford & Waterford. This time Clare, Kerry and Galway and we have had the warmest of welcomes in all areas we visited.
On this visit we were looking at gravestones in a cemetery and got into a conversation with a local lady who asked what I was looking for. I gave her all my info and she asked for my phone number and offered to search the local registers and let me know what she finds. I don't think you can get any more friendly and helpful than that.
The potato blight was introduced to Ireland by imports from America. The problem was that potatoes were the main crop as they offered all the nutrients needed in one vegetable so when the blight hit there was no alternative food. England and other countries, especially India sent copius amounts of foodstuffs but the distribution of this to remote parts of the country was a huge problem as Poorhouses were only built in towns. Having read several books on this subject I have never come across blame being laid at England's door entirely.
It would be a shame to let one bad experience deny you experiencing the many charms Ireland and her people have to offer.
The National Library in Dublin is a minefield of information for the genealogist
http://www.nli.ie/new_what_res.htm Many of the parish records are held on film there. On each visit I spend a day there whilst hubby walks his socks off in Dublin and have found loads of info, you just have to trawl the films of any parish you think may be useful to you.
Sorry you feel you had a bad time Jillie but I can assure you it is not the norm.
Can't wait for next year, Donegal here we come.
