Fig. 1. Fine-scale familial relationships and patterns of individual mobility between early Celtic sites.

The map shows the locations of the reported sites in Baden-Württemberg, southwestern Germany (n = 7). The ellipses and arrows on the map indicate the approximate geographical origin areas and general directions of individual mobility based on new and previously published strontium and oxygen isotope values from 67 individuals³⁷. Supplementary data can be found in Supplementary Fig. 2.8. Additionally, the site plans of Magdalenenberg (MBG), Eberdingen-Hochdorf (HOC) and Asperg-Grafenbühl (APG) are shown, as well as the dates of their respective central burials (red colour at MBG indicates cremation burials). The sex of the sampled individuals, the respective sample IDs (without site prefixes) and detected familial relationships are indicated. Supplementary data can be found in Supplementary Figs. 2.1–2.3 and Supplementary Tables 2.1–2.4.
