Parks,don't waste your time looking for ancestors,you will end up chasing your own tail.The street I was reared in had 6 houses with wilsons in them & 2 with stephenson.H&W employed more wilsons,thompsons & stephensons than you could poke a stick at.Stick to the pubs,more fulfilling & you will more than likely meet a few relatives.After all,everybody in ireland has a relation whose's a septic!lol.Keep flying that flag,cause you have more right to fly that flag,than to fly the other one.Sixteen presidents of USA can trace their ancestory back to NI.
I have a few rellies(2nd cousins),living in warroad minnesota & kenora canada,just across the lake.
If you get to belfast,give me a shout & I will point out a few good pubs.
all the best.
