Devine Surname DNA Study


Who Should Join and Why


If you are a Devine who knows where your family came from in Ireland, you can help this study. If you're still searching for an ancestral place of origin, perhaps the study can help you. Our objective is to determine whether Devine families that came from known Irish localities are related, and if so, how closely. We initially test Y-chromosome DNA at 37 markers, and when close matches are found, then at additional markers up to 67. Families are eligible to join if they bear any variation associated with the surname Devine, including Divine, Devin, Diven, Ó Duibhín, Ó Daimhín, Mac Dhuibhín, DeVine, DeWine, Devenney, Divinney, Davin, Dwane and Duane.


Current Findings


We now have results from over 80 Y-DNA samples from men named Devine of sosme variant of it--most tested at 37 or more markers, which helps differentiate closely related lines. Most of them belong to the major population group called Haplogroup R1b1b2, and their results are shown in four clusters based on matching or similarities in marker patterns. A fifth cluster includes the few who belong to the population haplogroup I. Those in Clusters 1, 3 and 4 are closely enough matched that all probably descend from a common ancestor who bore a hereditary Irish surname that has been anglicized as Devine or some variation of it.  The test results grouped in Cluster 2 are less closely matched, and while some may be nearly enough related to each other to have had a common Devine ancestor, the likelihood is that the cluster represents several different families, each descended from a different Devine founder.


Some families come from known Irish localities, but others are first of record only in the U.S. or Canada between 1700 and 1850. While their Irish origins are not yet known precisely, many of them match closely to families with known localities of origin in Ireland, and probably came from the same areas. Results for the entire project appear on the Results Table. It represents an update to the earlier published report “Sorting Relationships among Families with the same Surname: An Irish-American DNA Study.” National Genealogical Society Quarterly 93 (December 2005): 284-293, a special “Genealogy and Genetics” theme issue.
