Distribution of Germanic paternal lineages in Europe
This map was computed by adding Germanic lineages associated with the diffusion Germanic peoples from the Iron Age onwards. These includes Y-DNA haplogroups I1 (except some subclades of Finnish origin), I2-M223, R1a-Z284, R1b-U106, and R1b-L238.
Combined Celtic Y-DNA haplogroups
Distribution of Celtic paternal lineages in Europe
This map represents the paternal lineages associated with the spread of Proto-Italo-Celtic people from Central to Western Europe in the Bronze Age, starting circa 4,500 years ago. Their lineages are R1b-S116, in other words most of the European R1b minus the Greco-Etruscan R1b-L23, the Germanic R1b-U106 and R1b-L238, and the Proto-Celto-Germanic L11, L51 and L150. S116 includes subclades associated with non-IE languages such as Basque, and the ancient Gascon and Iberian languages. Since it is unclear exactly when and where Celtic languages developed and whether some Proto-Celtic speakers might have adopted indigenous languages in the land they settled (especially in Gascony and Mediterranean Iberia), all lineages were included for the purpose of this map, giving priority to Y-DNA over languages.
