When you view the Ethnicity breakdown by parents, be careful in your interpretation to others. The system can only show parts that you inherited! It is accurately split by side, but it is only showing the 50% that you received and retained from that parent.
A given parent had 50% of something else that isn’t showing and we don’t know what that is unless you test your parent.
Perhaps my Dad was 50% Prince and my Mom was 50% Princess and I only inherited the Leprechaun-ish stuff.
