A focused population profile of Bretons from Finistere, their western Brittany background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Bretons from Finistere come from the westernmost department of Brittany, facing the Atlantic at the far end of northwestern France. Finistere has strong maritime, rural, Catholic, Breton-speaking, and Atlantic regional history, with links to older Armorican and Brittonic settlement.
French is the main language today, while Breton is a Celtic language historically rooted in western Brittany. Finistere is especially important for Breton identity because it includes some of the strongest historical Breton-speaking areas.
As a genetic reference, Breton Finistère is useful for comparison with English, Welsh, Cornish, Manx, other Breton regional references, Dutch, Scottish, Irish, and Atlantic northwest European populations.
In the World Genetics modern G25 comparison, the closest non-self match for Breton Finistère is Anglo-Canadian Newfoundland and Labrador. Other nearby references include English, Anglo-Australian, Welsh, and Anglo-American Utah. This gives the Breton Finistère profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Breton Finistère is best interpreted as a western Breton and Atlantic northwest European profile, with English, Welsh, Cornish, Manx, and nearby Breton references.
The heatmap should emphasize Finistere, Brittany, Cornwall, Wales, England, the Isle of Man, Scotland, and nearby Atlantic/North Sea references.
The closest non-self match in this World Genetics comparison is Anglo-Canadian Newfoundland and Labrador. Other nearby references include English, Anglo-Australian, Welsh, and Anglo-American Utah.
In the current modern G25 reference set, Anglo-Canadian Newfoundland and Labrador is the closest listed match to the Breton Finistère average after removing Breton Finistère itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Breton Finistère G25 average, giving the closest-match results a geographic view.
