Seventeen individuals sampled from Tarquinia (400–1 BCE) offer a maternal-focused glimpse into this Late Etruscan community. Mitochondrial haplogroups observed include H (5 individuals), T2e (3), U (2), HV (1), and H5 (1). The prevalence of haplogroup H aligns with broad patterns across Europe in the first millennium BCE, reflecting continuity of common maternal lineages. T2e and HV are commonly found in Mediterranean populations and can signal connections through maritime networks; haplogroup U is often associated with deeper European hunter-gatherer ancestry and appears sporadically in later populations.
No consistent Y-DNA signatures are reported for this dataset, limiting direct inference about paternal lineages and male-mediated mobility. Genome-wide contexts from broader Etruscan studies suggest a mixture of Anatolian Neolithic-derived ancestry, local hunter-gatherer components, and varying levels of steppe-related ancestry — patterns typical of Iron Age Italy — but these are general trends and may not apply uniformly to the Tarquinia burials. Because the sample set is modest and geographically concentrated, conclusions about population continuity, migration, or social structure must remain cautious. Archaeogenetic results here are best interpreted as complementary to the archaeological record: maternal lineages indicate links to Mediterranean and European gene pools, while funerary practices reveal the social choices that shaped who was buried where.
