I think I read a year or two ago that some man up in the Yorkshire Dales is the most direct living descendant of the former tenant of a Stone Age skull unearthed not far from where he lives. It's hard for Americans to understand how much archaeological evidence 4 or 5 thousand years of relative dense settlement can leave. You probably can stick a shovel (or a Bobcat) into the soil just about anywhere in England and come up with something of interest. The Barbican area of London, where the old Roman and pre-Roman structures were exposed by the Blitz, is fascinating.
