It's based on samples from Corded Ware, BB, and early Bronze southern Germany. I'm trying to figure out some way of getting access to the whole paper.

"Abstract

Revealing and understanding the mechanisms behind social inequality in prehistoric societies is a major challenge. By combining genome wide data, isotopic evidence as well as anthropological and archaeological data, we go beyond the dominating supra-regional approaches in archaeogenetics to shed light on the complexity of social status, inheritance rules and mobility during the Bronze Age. We apply a deep micro-regional approach and analyze genome wide data of 104 human individuals deriving from farmstead-related cemeteries from the Late Neolithic to the Middle Bronze Age in southern Germany. Our results reveal that individual households lasting several generations consisted of a high-status core family and unrelated low-status individuals, a social organization accompanied by patrilocality and female exogamy, and the stability of this system over 700 years."
