At an excavated African workers village in Seville on the North coast of Jamaica there were keys and large padlocks in the buildings indicating there was a lot of material wealth.
As he pointed out the wealth is not surprising when you remember that the slaves create the internal marketing system. Many slaves were wealthy during slavery. Their wealth came not from handouts from planters but from their work in the grounds, their trading and their farms in the hills.
From oral tradition it was known that there was a close relationship between Africans and native Arawaks who were called Taino. Now DNA evidence is showing that the maroons carry a lot of genes of the Taino people. The African male slaves who escaped took Taino wives and those were the people who became the maroon population.
Hard to say much about that. Interestingly, it was only a few years ago that I learned that 'maroon' -- you know the Bugs Bunny line, "What a maroon!" -- was actually these slave descendants. Supposedly it has a negative connotation. I still kind of wonder if Bugs was really referring to these Maroons and not just purposefully mispronouncing 'moron'. Which is what most of my acquaintance thought.
