Devine ancestral lines, variously spelled, are being sorted and matched through their distinctive DNA patterns, and associated with the Irish places where they were first known. We are also linking Devine lines of unknown origin to localities in Ireland where matching DNA patterns are found.

To extend our initial findings, new members are welcome, especially those with known family origins in the area where most Irish Devines are clustered--from Strabane to Derry in Counties Tyrone and Londonderry, and in the adjoining area of County Donegal--as well as from smaller Devine clusters in Counties Cavan, Leitrim, Longford, Louth, Mayo, Roscommon and Sligo.

Some project members, both men and women, have ordered mitochondrial DNA (mtDNA) tests to identify maternal line ancestry and perhaps match to others with the same ancestry. While not formally part of the Devine study, earliest known surnames in mtDNA lines are also listed alphabetically among the Devine variants.
