Welcome to the British Isles DNA Project

The British Isles DNA Project is a dual (Y-DNA and mtDNA) project that is open to persons with a documented direct paternal or maternal lineage originating in the British Isles. You may join if you have identified an ancestor who lived in the British Isles, with  a name, the time he or she lived and a specific place (town or parish, and county). A direct paternal ancestor is a father's father's father's..... father. A direct maternal ancestor is a mother's mother's mother's .... mother.

For the purposes of the project, the British Isles include England, Ireland, Scotland, Wales, the Channel Islands, and the Isle of Man. The British Isles DNA Project is intended to supplement, not replace, existing regional or county geographical projects for Great Britain and Ireland. Members of other surname and geographical projects are therefore welcome to join.

Aims

The aims of the British Isles DNA project are twofold: first, to aid genealogists in the task of identifying ancestral origins and distribution of descendents; secondly, to assemble a detailed haplogroup map of the British Isles by county, corresponding to the DNA profile of the region's early history and settlement.
