Those Ancestors that were in n physical bondage, what type of labor were they forced to do? Mine work? Lumber work? Cotton? Landscaping? Engineering? Cooking? Cleaning? Driving? Driver work (aka work), Iron work? Tobacco cultivation? Rice growers?

The majority have no idea and that is by design. Well. U should know and u should know what that bigger picture turned into... u should know EXACTLY what big business came from ur Ancestors blood labor.

The best way to start that process is write down ur Ancestors names until u get back to one living in 1940 n then find that person on the 1940 census. A family history site like http://familysearch.org  can be used for this. It is "free" in the sense no money is needed to begin.

Were they in a large city in the South, North, West?? Are they in a rural area? Were they in the place they were born in. If no, why did they move there? If yes, why are they "still" there? Did they own that land or renting/sharecropping? These are the type of ?? u must answer.

If u get stuck or want to go further back, hit me up in this thread.
