They Traced Welsh Surnames Across the Atlantic — What the DNA Revealed About the Original Britons!

Long before the Anglo-Saxons, the Welsh were the Britons: the original Celtic-speaking people of the island. The People of the British Isles study (Nature, 2015) found them among the oldest and most distinct genetic groups in Britain. This documentary follows that ancient signal, haplogroup R1b and the marker L21, the Welsh Tract of Pennsylvania, and the patronymic surnames Jones, Evans and Williams, across the Atlantic, comparing Welsh-American DNA to modern Wales. How much of the original Briton survived the crossing? Sources (real, working links): 1.
