I'm into DNA. I have tested possitive to a genetic marker called
R-L21. Half of Irish males tested so far are possitive to this marker, indicating a possible common ancestor from the Bronze Age.
This marker is found along the northern Alps also, indicating a possible sw/german/swiss/Northern Italian origin.
This field is still unfolding as they search for new dna markers to test for.
Amonst my genetic matches I have genetic relatives who are Murphy, and Phalen also. It's an interesting hobby.
I hope some day to match genetically with an O'Connor in Ireland.
There is a nice trad music session in The Roaring Donkey pub in Cobh on a Wednesday night if you are in town.
This website shows the list of cruise liners due to visit Cobh this year, these ships always add a buzz to the town if you can schedule a visit around them.
