Welcome to the home of the Fitzpatrick DNA project
This site provides Y-DNA results for men with the surname Fitzpatrick and autosomal DNA results for both men and women with an association to Fitzpatricks. This site was inspired by the pioneering work of two of our own - Dr Colleen Fitzpatrick and Dr Ronan Fitzpatrick. The study began in 2000 and was the first to identify several genetically distinct groups of Fitzpatricks. Originally organised through Relative Genetics, the study includes more than 300 Fitzpatricks from Ireland, the United States, England, Scotland, Canada, Australia, New Zealand, Barbados and France and is now hosted at familytreedna.com.
Fitzpatricks are genetically diverse. The largest group identified by Colleen trace their roots to County Laois. Other distinct groups include individuals who trace themselves to County Cavan, County Clare, County Cork, County Down and County Kilkenny. This accounts for approximately 50% of the study's members. About a further 25% fall into small groups of unknown origin, and the remaining 25% have not yet found matches within the study - although some have had success with matches on other surname projects.
As well as the DNA content this site also provides some history of the name Fitzpatrick, some Fitzpatrick stories - both old and new, and a section on interesting Fitzpatricks from around the world.
