The initial phase of the Elp culture (1800-1200) in the Low Countries is characterized by tumuli related to the Tumulus culture and later to the Urnfield culture, with Dutch-German lowland areas found to share cultural roots with the southern Scandinavian area [Butler, Arnoldussen, and Steegstra 2011/2012] predating technologic and economic exchanges between Urnfield and Northern Bronze Age Scandinavia [Kristiansen and Suchowska-Ducke 2015].
These complicated cultural-economic networks that preclude precise ethnic (and thus linguistic) differentiation, supports the maintenance of late contacts between the languages ancestral to Germanic and Celtic, assuming a position of Proto-Celtic to the north of the Hallstatt culture – as supported by the known homelands of La Tène culture.
Lacking aDNA samples to obtain admixture analysis, careful investigation of I2a2a-M223 lineages – found today distributed among Germanic and Italo-Celtic territories – might bring light to population movements and exchanges during the Bronze Age and the Iron Age in Europe.
