I am 1/2 Irish, 1/2 German.
But 23andme has it broken down differently:
52% British and Irish (Merseyside and County Galway)
16.5% French and German (Saxony and Switzerland)
4.3% Greek and Balkan
15.7% Eastern European
2.8% Broadly European
<2% Neanderthal
0.3% Ashkenazi Jewish
I don't know how those different places popped up. 23andme updated the report a year ago.
My mother's family has been in Saxony since the 1700s - which is as far as her ancestors were checked. I assume by the Nazis, because she escaped from East Germany when she was 18.
My Dad's great grandparents came from County Galway. I found them on a US Census thing.
I was expecting to have Native American blood, but did not. The standard story in our family was that my dad and his siblings were 1/4 Native American (Shawnee). When my DNA was tested, nothing there. I called my cousin and told him. He said, "Well, you're from the milkman, then." Which was a joke. I thought it was funny, but my mom was outraged. Basically, my large Irish side of the family is still convinced about the story.
Anyway, I was disappointed because since I was a little girl, I have been interested in two groups: Native Americans and Jews. By interested, I mean I read a lot of fiction and nonfiction books about them. I was surprised when my father married a Jewish woman, and she told me that I knew more about being Jewish than she did! I was 16, and I gave her a book on the subject for Christmas.
Once, I made contact with a relative through Ancestry.com because she had asked about specific relatives that were mine. She also thought we had a lot of NA blood, and wanted to know if I knew my grandmother's father's name. He was allegedly the NA. So the story has been around for a long time. That woman would be over 100 years old now.
Anyway, what I know about genetics could fill a thimble.
