I had my Blood Type A Secretor confirmed with a friend about 25 years ago. I didn't know I could have had a DNA profile done as well. It's a pity no firm in the UK offers the service.
During lock down, I subscribed to My Heritage DNA -because it was being offered at half price!- sent off my details and waited in eager anticipation. When the results came back, they informed me that my DNA is 49% Italian! The only feedback I've received since suggests potential links, mostly to Cypriots, with a smattering from USA, and one from New Zealand, all being named as being related to 3rd/4th cousins!! In the meantime, via a genealogist and FaceBook, I've located, and since met, a niece and nephew who are the the offspring of my late sister who, sadly, I never got to meet.
My advice is, there maybe better, and more accurate, ways, than My Heritage, of tracking families!
