23&me--My Ancestry Timeline

I think the long generations in my family may have thrown this off a bit.  

My parents were born between 1930 and 1940.   

My Grandparents were born 1888-1899.  

My Gr Grandparents 1853-1875  

My 2nd Gr Grandparents 1808-1820

My 3rd Gr Grandparents. 1772-1800(There are 2 in my patrilineal line I have not yet identified)

I have not identified any North African ancestry though multiple companies have shown some trace amounts and ancestry similar to Sephardic Jewish.  

Their white paper on the process is available here
