As you view ethnic origins, remember that the DNA you inherit from your ancestors is passed down to you in an unequal ratio- you carry more DNA of some ancestors to the detriment of others. Plus, MyOrigins and any of the other available tools (such as 23andMe's Ancestry Composition) that estimate your ethnic makeup are based on the program's unique formula and estimates.
The European designation can be further broken down into areas. The result is that his ancestry hails from all of Europe, with half from the Coastal Islands- Britain and Ireland.
My mother's results paint her as three quarters Coastal Islands and one quarter "Jewish Diaspora," centralized in Poland.
Looks like some refinement is necessary to capture the missing heritage.
