I'm using my heritage no surprises so far they use European data which is why I picked them. One thing I have learned as a quality engineer data quality matters including sample size and what you sample basically like in polling your sample is determined by people letting themselves get sampled, So far in my case only two first cousins have taken the test, none of my wife's cousins have, probably none have a reason too What I am noticing is no reason no test. One of my first cousins was given up for adoption by my aunt 65 years ago. My mother had told me about him before she passed away. I joined to sort out a few mysteries. discovered even bigger mysteries.
