BBCnews is carrying this report summarizing the dating of what has proven to be the oldest cemetery in Britain. Dated to roughly 10,400 to 10,200 years old, it goes right back to the Mesolithic era, and probably represents some of the first people able to live in Britain... the glaciers had only just retreated from the island. In fact, they're not completely sure it was an island at that point. Sea levels may have been low enough to allow a land bridge between Britain and France, letting people walk back and forth freely.
