The DNA of Clan O’Brien (Dennis O’Brien)

The O’Brien surname is one of the most common in Ireland and the O’Brien DNA Project is one of the most mature Surname DNA projects in existence. Dennis discusses the DNA results of the project, how the O’Briens are genetically related to the rest of the Dál gCais, differences and synergies between SNP & STR marker results, and the implications of the DNA results for the future of O’Brien family tree research. He is joined in the Q&A session by the Clan Chief - The O'Brien, Conor, 18th Baron Inchiquin, Prince of Thomond. This lecture was presented at Genetic Genealogy Ireland 2016.
