Black is simply a term that identifies anyone who is African descended no matter where they are from. It's a very broad description. I understand many Africans who are more so directly from the continent instead identify with an African country or African tribe instead of the word black. Those of us African descended people who are located in the western hemisphere as a result of European enslavement use it as a way to acknowledge our African even though most of us are very unaware of the tribe or even simply the country we derived from

I am a Black American and have recently found interest in tracing my Africa roots like many of us have. I've also been able to get a few friends to do it along with me. We are just currently researching the best company to do it with. My family comes from South Carolina and are a part of the Geechee/Gullah groups also known as Sea Island Creole and ive heard much of out lineage traces back to Angola but also Senegambia, Congo, Biafra and Guinea first by way of the west indies.
