My new Ancestry results are as follows; 61% Irish, 27% English, 6% Welsh, 6% Swedish/Danish.
Looking at my papertrail and going by my 64 4xgt grandparents (some are estimated because I haven't got back that far), I have 55% Irish, 28% English, 5% Welsh, 6% Scottish and 6% Unknown. Interestingly, and I may be reading too much into this, my Unknowns were named Anderson and just remotely possible that they came from Sweden or Denmark.
Anyway, even ignoring the smaller percentages, I'm quite impressed by how accurate my "ethnicity" breakdown seems to be.
I am a bit suspicious though that all my chromosomes (apart from chromosome 6) are all pure English, Irish, Welsh etc. So for example, my chromosome 1 contribution from my mother is entirely Irish while the same chromosome contribution from my father is all English. On the other hand, my chromosome 6 contribution from my mother is about 80% English and 20% Irish while my chromosome 6 contribution from my father is about 90% Swedish/Danish and 10% Irish. Even the Welsh contributions are wholly concentrated on just three chromosomes, yet my Welsh ancestors were born in 1700's - plenty of time for the chromosomes to get fragmented. Perhaps I just don't understand how it works
