Happy to hear that you are Belgian, we are the best ... in beer and chocolate ... and we manage the Ineos Automotive spare parts warehouse too.
I took 3 ancestry tests, two confirmed what I knew: half Walloon and French and another half Dutch and Flemish.
Another one was indeed completely flawed: half British, half Dutch, and nothing (0) in France.
And I have my ancestry tree almost complete in all branches till the early 1600! (More than 1000 couples).
If you PM me your last name, I can perhaps tell you if it is rather French or rather Belgian.
