I heard about Negroland a few years ago, from watching the videos from the late Steve Darby, including the one in the OP. It's true, most of us so-called African-Americans are the real Hebrew Israelites the Bible speaks of, and we descend from Shem, not Ham. So our forefathers come from Israel, not Africa. As already stated in this thread, the area Negroland was formally known as, "The Tribe of Judah". The Lion Tribe of Judah is the tribe Jesus Christ descended from, who's real name is Yahawashi (Hebrew). Judah was one of the 12 Tribes of Israel, and the forth son of our forefather Jacob. I'm glad more of us are finally waking up to who we really are, and finding out how much information has been kept from us.
I don't want to overwhelm anybody just finding all this out, but also a lot of us, arguably most of us, were already here in America before the slaves arrived, and we were called Indians. A lot of us here descended from these native Indians, who were darker-skinned, not like the Indians we know today. These native Indians descend from Gad, Jacob's first son. These native Indians are also Hebrew Israelites. To sum it up, the native Indians are a part of the Northern Tribes of the Hebrew Israelites, and the so-called African Americans are a part the Southern Tribes of the Hebrew Israelites. Judah's brothers, Benjamin and Levi, are the forefathers of the remaining two Southern Tribes, with Benjamin's descendants being the so-called Jamaicans, and Levi's descendants being the so-called Haitians.
