http://www.oxfordancestors.com/Although it doesn't relate to what you're looking for specifically, it can trace your ancestral genes by thousands of years. I've used a MTDNA (motherline) search and found who my ancestral mother was 10,000 years ago. There is also a DNA test via surname search, a new "tribes of Britain" test and one for Y-chromosone (fatherline) and these are found under the site's shop.
