When I originally got my ancestryDNA results I called her up like ummm Granny there's no readings of Native American in my blood, not even a trace.
I remember her telling me that her mother was partly NA, so it confused me as to why a trace of it wouldn't come up in my test. I mean that's my great grandmother, not my super duper 20th great grandmother from prehistoric times.
But there is a trace of Native American in the test, I think I was so focused on the African and European contents of the test -- because they were the strongest traces --- that I didn't pay attention to anything else that popped up.
It may not be as strong as my grandmother's trace would be, but it shows that she wasn't talking under an assumption. DNA shows that it is in my bloodline. I was initially kind of disappointed because I felt like my grandmother was too educated on her family not to know where our bloodline stems from, but at the same time, DNA is so sporadic and unpredictable in its distribution that I didn't want to flat out tell her that it doesn't exist in our family simply based off of my individual test..... it may not have shown up for me since I am one generation separated from her.
She's gonna lash the hell out of me.
