I want to start by acknowledging that this is a sensitive subject for many people and to say that in no way do I want to trivialize the abuse of enslaved people. History books frequently mention female slaves being "brought up to the Master's room" as though it were a commonly accepted practice at the time. Are there records of how the wives of the owners reacted to this?
The attitude of wives to their husbands rape of enslaved women ranged between willful ignorance and malevolent jealousy. This has been expanded on previously here.
