I think what you mean is : do I have any black ancestry? Descendants are people who descend from you. That is an interesting question. I know I have because I have photographs showing my great-grandmother is bicultural. Do you have features or photographs of ancestors which might indicate that there is black blood? Or have you heard family stories? If you do, then the first thing to do is to start working on your family tree, starting from yourself, recording all brothers and sisters, and going backwards. I do not know what coun,,try you are in, but if you are in a country that has been settled within the last 300 years, then the chances are that the union you are looking for has taken place within that time. Get back to me if you need help. Depending on where you live, I will do the best I can. Cheers
