We'll he owned her and he or one of his relatives is the father. So his relatives came in and did the deed with her in his home and TJ didn't know. Was this because he was out of town and his relatives had free run of the house...........slaves.
The scenario where he doesn't know doesn't seem very gentrified to me, thus my two choices.
My impression is that he wasn't the most hands-on master (no pun intended!).
