Not knowing which ethnicity pops up hampers my reply. if it is Scandinavian and you are mostly from the UK I would not put much crepe dance in it. However if it is showing African than it is likely quite real. or if it is Jewish or any of a number of other populations that are easy to discern.
if you don't feel comfortable sharing publicly. Feel free to drop me a message. lots of folks get surprises. I did but it didn't show up here.
