Examining my mother's known ethnic heritage I was able to breakdown her father Charles Forgey's ethnicity. He was mainly Scottish and German. He may also have had some English ancestry, but I have not been able to make that connection.
I was not able to breakdown her mother Graciela Del Castillo's ethnicity. Nicaraguans have a high percentage of Iberian and Native American ancestry, with a smaller percentage of African. It's been difficult for me to trace our family back in Nicaragua beyond the late 1700's. The surnames I have so far are all Spanish.
Looking at the 23andMe result the British & Irish seems low? I would think this would be at least 38%? Although it's possible my mother may have received a higher percentage of DNA from her German ancestors? There is a 7.80% Broadly Northwestern European number, which could reflect either German or British ancestry, or a little of both? There is also a Broadly European result of 6.10%, which could trace to anywhere? There is also an unassigned amount of DNA. The 34% is close enough for me however.
I'm very happy with the high Iberian percentage number here. It makes more sense than the results from the other companies, considering her Spanish family surnames, and her many matches with Spanish surnames. There is an unassigned Southern European 10%. Could that be Italian? I doubt it. It may reflect ancient shared Southern European ethnicity that came down through the generations?
No Scandinavian in these results also makes sense.
