In twenty years time, I imagine that our ethnicity estimates will be very different to those given today. My DNA matches my tree back to at least 5 generations, with EVERYONE born south of the Wash, but I have 11% Scottish DNA. This is either wrong, or represents lots of vestigial scraps.

Pure racial DNA would depend on finding people whose ancestors NEVER moved. This is nigh impossible.

You also have the problem that each DNA testing organisation will describe populations in slightly different ways, and have different sample sizes.

Each ethnicity upgrade on Ancestry gives a different mix for me. I have briefly had French and then various Scandanavian ethnicities. I think we have to treat ethnicity as a bit of fun, and certainly the current results are fairly suspect.
