There are a lot more cases of slave merchants families. In present day, some of these families are the richest in the continent.
The richest family lineages in Angola, used to own slaves. Mainly the Van-Dúnem family.
Van-Dúnem are the product of a Dutch slave trader who went to Angola, married with a local woman, had multiple kids, and their kids also became slave traders.
Then you have cases like the Dos Santos family, Vieira Dias family, Pinto de Andrade family and a lot more.
Dos Santos family is a mix between portuguese and angolans. Funny part is, many of the members of these families(Van-Dúnem, Vieira Dias and Dos Santos), ended up marrying each other.
And, they were not only trading in Angola, they were also trading slaves in São Tomé and São Tomé. Some of the Van-Dúnem kids went to make a fortune in São Tomé and Cape Verde, as slave traders.
Our last president,
José Eduardo Dos Santos, is also part of the Van-Dúnem family, but the São Tomé's branch. Something that he tried to hide for years.
This is a book that relates the story of the Van-Dúnem family. The author, a portuguese-angolan, by the name of Pepetela, had to change the real names. He was getting a lot messages from the powerful family.

Angolans, in general, do not trust creole or mixed people, not only because of slavery, it is because in our biggest revolutions, they mostly stayed on the other side. Even the ones with black fathers. It wasn't until they saw that the Portuguese were about to loose, that they decided to fight with the native population. And in places like Cape Verde, they still practice a caste system.
