I used 23andme which is a service that analyzes your DNA to provide me with my ancestry composition. Below are the details from the report they’ve generated.
I know that my Grandfather fled Poland during World War II to Argentina and surely is why I’m 44.6% Ashkenazi Jewish. I also recall meeting my Great Grandmother in Argentina who came from Italy which I believe is contributing to the 22.4% Italian. Other than that I don’t have any other insights into the report.
