I am an Afrikaner from South Africa. We are the most mixed you can imagine. The Dutch settled the Cape, brought Germans along, and the first generations married Malay, Indian and black African slaves and the native Khoi. Later some French refugees came and then the British conquered us and settled a fair bit. Then there are the odd adventurers coming around. Funny thing is, we then institited racial segregation policies? My grandmother worked out all the collateral lines of descent from arrival in South Africa, then fudged nice European descent when she found something she didn't like. My father and I then had to go back and correct her work.
My ancestry is mostly Dutch, German and French ... However, I have Khoi from the Cape, Angolan, West African, Malagasy from Madagascar (with admixture of Arab), Indian (Coromandel Coast and Bengal mostly), Malayan, Timorese, English, Scottish, Danish, Italian (Some Savoyard Huguenots and a guy from Calabria), Portuguese (from a shipwrecked sailor that settled down) and that one random Chinese guy that ended up at the Cape in the 1700s.
