Hope you doing well. No I have not had any luck at all. I don't think lots of people actively participates on the website.
I am from cape town, with my grandparents originally from Paarl, Western Province. Right now I am living and working in London. I am mixed race and I am sure that my forefathers were part of the French Hugenots that come to the Cape. They must have 'mingled' with the locals or the slaves at the time .... and hence the mixed race was born.
Where are you, and have you had any success. Let me know.
