Project Goals
The McCarthy Surname Study will attempt through Y-DNA analysis to compare individuals with surnames common to the McCarthy clan for similarities and differences. It is hoped that distinct patterns will emerge that will allow McCarthy men to discover from which branch of the McCarthy tree they are descended. It is also hoped that these distinct patterns will eventually lead us to specific geographic areas of Ireland. For the many McCarthy males who do not know where their McCarthy ancestors lived in Ireland, this would be an exciting path for future research.
