Yes, in the form of thousands of African slaves (visible more via their absence, but showing up obliquely in complaints about "the cadavers of the blacks" being eaten by hyenas). Suffice to say that they were not coping well either, since Angola at this time was one of the centers of the Atlantic slave trade. The only person in these letters who seems at all calm is Queen Nzinga of Ndongo, an independent African ruler who communicated with the King of Portugal via a couple letters. But her family again proves my point - her brother, the former ruler, committed suicide due to his grief at his kingdom's loss of power. 17th century archives are basically a non-stop litany of enslavement, murder, illness, and complaints about lack of basic necessities.
The one exception among the archives I've looked at are those of the Royal Society - but then again, those archives describe medical experiments that would be considered completely appalling today (like trying to replace a madman's blood with that of a sheep). People might be resilient, but by and large they were not having a good time in this period, and they knew it.
