I1-Z62 Continental North Sea branch
I1-Z62 is a continental North Sea branch of the I1-DF29 lineage that splits from the broader I1-Z59 framework. It probably formed in the Late Nordic Bronze Age or early Iron Age among populations inhabiting the North German plain, Jutland and the coastal Low Countries. The clade marks an early differentiation of inland and coastal Germanic groups that would later participate in Anglo-Saxon, Frisian and related expansions toward the North Sea and British Isles.
Modern carriers of I1-Z62 are most common in Germany, the Netherlands and Denmark, with elevated frequencies in coastal regions of the North Sea and lower Rhine. Lower but clearly detectable levels are found in England, particularly in eastern counties settled by Anglo-Saxons, and in southern Scandinavia. Sporadic occurrences in France, Iberia and overseas diaspora populations reflect medieval and modern migrations.
I1-Z62 branches under I1-Z59 and is closely related to I1-Z60. The defining mutation Z62 marks an early split within the continental DF29 radiation, from which several regional subclades descend. Compared with very large radiations such as L22 or Z63, Z62 shows moderate but geographically coherent diversification.
I1-Z62 is an important marker for early continental Germanic and North Sea coastal ancestry. Its distribution complements related branches such as Z60 and provides a finer scale view of the paternal background underlying Anglo-Saxon and Frisian movements.
