Three Irish men were buried under a Pub [cymbal shot] But seriously, three Irish men were buried under a pub. Here's an interesting video interview starting with Lara Cassidy and leading to Dan Bradley. It's embedded from the NY Post story:
Everything from Britain and Ireland first passes through the lens of Celtic identity, or at least the 19th Century's formulation. The Rathlin burials demonstrate that the modern Irish genome was effectively established by the Early Bronze Age (something I had predicted for much of Europe) and gives a little fodder for Koch and Cunnliffe's theory of "Celtic from the West". The latters propose a MBA Atlantic network leading to the formation of Celtic, but I don't believe they define from 'what', eg. more basal IE dialects or something else.
Another paper should be out this year that will challenge Koch and Cunnliffe on the details, but argue something similar; essentially that historic Celtic lacks a center of gravity specific to the Urnfield to La Tene circulation and was rather widely dispersed among Continental and Atlantic Bronze Age trading villages, or something to that effect.
With regard to the Beaker phenomenon and language (assuming its common language never changed), I'd be careful to avoid making that shoe fit. There probably was a semi-intelligible, pan-European linguistic affinity among far flung Beaker settlements but it may be more something like 1) not European at all, or 2) something ancestral to the entire Centum branch.
