Actually I'm thinking about it. My cousin did it last year thru Ancestry. I think there are 2 packages you can buy. She sent me what was a pie chart with percentages of backgrounds. She was 77% Italian and small percentages of Black, small percentage European (?) and another 2 or 3% undetermined. It is interesting. Also, if they discover any relative of yours with the same dna they'll notify you.
I know my family history for the most part thru Great-Great grandparents on both sides. Always say I'm full Italian (all grandparents born there as well as my father). However, there's likely some other heritage down the line.
My intention was to get a DNA kit sometime this year. I still may, but seems like other expenses always comes up
