Atlantic Bronze Age (by Thierry kerneur) is a free Global25 ancestry calculator (Calculateur, G25, Scaled). Atlantic Bronze Age is a free Global25 (G25) ancestry calculator by Thierry kerneur. It uses Bronze and Iron Age reference populations. It models your coordinates with 109 reference populations, including Woman Scotland MBA Evergreen Longniddry, Woman Scotland LBA Covesea Caves Moray Covesea, Male Denmark BA, Male Wales MBA St Fagan's Wales Glamorgan lowEEF and Male Wales Great Orme Wales North Wales LlandudnoC EBA. Paste your scaled G25 coordinates to get your best-fit ancestry mix, computed directly in your browser. Its reference panel holds about 109 reference populations, grouped mainly as Woman Scotland MBA Evergreen Longniddry, Woman Scotland LBA Covesea Caves Moray Covesea, Male Denmark BA, Male Wales MBA St Fagan's Wales Glamorgan lowEEF, Male Wales Great Orme Wales North Wales LlandudnoC EBA, Woman Wales Great Orme Wales North Wales Llandudno MBA, Male Atlantic England BellBeaker Amesbury Down England Wiltshire highEEF, Male Atlantic England BellBeaker Amesbury Down England Wiltshire lowEEF.The panel was built or amended by Thierry kerneur.Last updated: June 2026 (version 2026.6).
People who already have their Global25 (G25) coordinates, for example from a raw DNA file converted with our G25 coordinates service, and want to see how a specific reference panel reads them. Different calculators use different panels, so the same person can get different percentages, and comparing several is more informative than trusting one.
Paste your coordinates, choose a run mode and start the calculation. Each result line is a reference population followed by the share of your ancestry it explains, the shares add up to 100%. Very small shares (below roughly 1 to 2%) are usually noise rather than real ancestry. The distance value tells you how well the mixture reproduces your coordinates: the lower, the better, and a high distance means this panel does not describe you well. For example, a result of "Polish 60 / Ukrainian 25 / Lithuanian 15" means your coordinates are best rebuilt from those three populations in those proportions, not that you descend from three separate groups.
