Searching for African American Ainsworths of the South

Hello. I am searching specifically for the African American Ainsworths of the American South, in particular the areas of Mississippi, Alabama, Missouri, and Texas. Some members of the family are starting to take DNA tests to find out if (1) our slave ancestors were the product of a white master and his slave or (2) the Ainsworth family adopted the name after they were freed from slavery. I know from reading the blogs that some Ainsworths were the product of relations between master and slave. Yet, we all have the same name, so trying to connect to see who is related. Thanks.
