Me and my brother visiting Stonehenge in AD 2003. Speaking of relatives in and around Stonehenge, here's a new (OA) paper with Jo Brück, @SelBrace & Ian Barnes based on findings in Olalde et al. (2018)

The main aim of this paper was to try to show off the wealth of useful information that can be found in the Supplementary Materials of large-scale aDNA papers, if you know where to look. These details are often not discussed in the main text, but can be pretty significant...

Olalde et al. (2018) found there was a yuge transformation (>90%) of the genetic ancestry of people in Chalcolithic-Early Bronze Age Britain (c.2450-2000) produced by movements of groups of people from possibly various parts of continental Europe.

Our chronological modelling of associated radiocarbon dates in OxCal suggests this ancestry shift was fairly gradual, probably taking between 311-472 years, or 10-16 generations.

Groups genetically continuous with preceding Late Neolithic groups continued inhabiting C-EBA Britain but we don't see them so much in the DNA data as they largely continued to cremate their dead or treat them in ways which left no archaeological record.
