My mom used to do a lot of genealogy, and discovered we had some New England sea captains in our ancestry. Some of them may have been slave traders, and I have been trying to find something in her papers that might confirm or deny this. Not easy to do, as she passed away some time ago, but I'm still looking. I'm hoping my sister might have saved some of those papers.

Have you looked into your own ancestry as regards to this issue? Bunce Island, in Sierra Leone, was a Slave trading post, and many natives of that area were involved in the slave trade. A large percentage of American slaves came through there. Your ancestors might have been both victims and perpetrators of this practice, and your current level of affluence could be a partial result of this. More likely perpetrators, though, as most slaves were captured inland by African raiding parties from the coast.

Of course their is nothing like an equivalence here. The wealth made by European enslavers was much greater than that made by their African partners. And their African descendants still have to endure the injustices of systemic racism in ways that don't affect any white person. But it's always good to know the nuances of a morally complicated truth.
