I am interested in the use of DNA (both yDNA and mtDNA) to help find family roots and connections. I am co-administrator of two projects: O’Shea Surname yDNA Project and the Ireland Heritage yDNA Project. Both these projects mainly use the Family Tree DNA testing company in the USA.
The International Society of Genetic Genealogy (ISOGG), is a non-profit society that is not affiliated with any commercial for-profit company, individual, or other such entities. It operates a message board for genetic genealogy at Yahoo.

Hello, I wondered if they did DNA to connect families in Co.Cork. I realise my hopes of finding some record of my family of Sullivans there is like looking for a needle in a haystack, having found loads of the same name.
Would a DNA test have any chance of connecting me with Sullivans there??

Hi Eileen,
There is a yDNA Project for the Sullivan surname at Family Tree DNA:
http://www.worldfamilies.net/surnames/sullivan/
If you get a male Sullivan in your family to do a yDNA test, he may find matches to Sullivans who have a paper trail to Co.Cork. This will confirm your connection to Cork Sullivans.
Best wishes,
Margaret

My Mother was from Skibbereen, and it turns out my mitochondrial DNA is rather rare for western Europe.
I am very stuck right now trying to sort out who my Great Grandmother was, as there were just too many women with the same name, roughly the same age and in the same general area at the same time. I have a probable marriage record from 1904 and a probable census record from 1911, but finding her in the 1901 census has proven to be just about impossible. Her husband is proving to be equally impossible to pin down.
I am thinking of writing to a few businesses in the area and even advertising in the Southern Star for matrilineal descendants of certain women, in the hopes I can learn a few family histories and find a few people willing to take a mtDNA test so I can determine once and for all which Hurley was my GGrandmother.

What haplogroup is your mtDNA?
Good luck with your research.
