Some people say ... Give some names, please.
I would love to give you some names, but I only remember reading about certain things, one of which being how the Pope "gave" Ireland to the British kings. Essentially the Irish were happy doing things they way they had been but the Pope was unhappy in that the Irish did not always follow his decrees and still celebrated Easter at a different time (IIRC), yadda yadda... So the Pope told the Normans to go invade and if they were "converted" Ireland would belong to England.
Accounts of such can be read herehttp://www.baptistpillar.com/bd0115.htm

not sure about this website (turned up in a search)http://www.ensignmessage.com/archives/popsirlnd.html
that website is weird all over
So, there are some places you can read about the supposed loss of Orthodoxy in Ireland due to Norman invasion.
Also, there are a few groups that call themselves Celtic Orthodox. A few here in the US and one I know of in France.http://celticchristianity.org/
here is a site for in the US, I almost switched to this church when I was a Protestant, but never did. I have emailed them to ask what their views on the EO is and if they would be willing to seek communion... No response. They also use the Lorrha Stowe Missal for worshiphttp://www.orthodoxie-celtique.net/who%20we%20are.html
another Celitc "Orthodox" church that claims to be the restored church founded by Joseph of Arimathea.http://www.monachos.net/forum/showthread.php?2912-Celtic-Orthodox-Church
this site has some info concerning certain Celtic Orthodox churches.
I post those sites to show that there are those interested in bringing back original Celtic Orthodoxy (i.e. the faith followed before RC in the Isles), or at least trying to profit from the Celtic craze. I wonder if they will ever seek communion with any actual Orthodox church instead of just using the name to draw people in...
and lastly, but not leastALBA GU BRATH!!!
