Both my parents sent did Ancestry and their results came back somewhat interesting I thought. They both were well over 80% "British" and my mom was 11% Irish. Most everything else was at trace levels. With that said, both of them can trace their families back a couple hundred years in the US(my dad to colonial frontier Kentucky) so I find it interesting that it would be that narrow.
With that said, the results themselves weren't that interesting. My mom "matched" as a very high probability of a relative with someone in Texas. The man had been born to a 16 year old mother and adopted. A bit more information(and another DNA match) established him as being my mom's nephew via her half sister. After 60 years, he was able to meet his biological mother. I'm not sure how often something like that happens, but it certainly wasn't something that she expected to come out of it.
