Maybe they did'nt call themselves celts, but in our neck of the woods, the celtic influence (Bath, Somerset,etc) is so strong that sometimes I think it is still floating round! Bath itself with its sacred spring dominated by the male celtic head is just one example, the juxtaposition of pagan roman temples within hillforts; the later celtic monks that seem to have established themselves around the Bristol/Severn channel right up to Hereford, and the later saxon incursion that overran and predominated this area, all seem to overlap in settlement, and probably in people. Strangely enough whilst out visiting friends in a remote hamlet on the Cotswold yesterday, they lived in Turkdean, vague thoughts that it was french but no it turns out that it translates back to the celtic, Valley of the Boars - Twrch = boar; dene = valley.. to go back to etymology.
