They're not your blood relatives. Sell them as sex slaves and move on with your life. Might ask fly...
They still have a dad, so I'm not worried about them, per se, aside from them having to watch their mom die. My point is that life is about more than boots, and anyone who doesn't realize that should pack up and move out into the wilderness to be eaten by Indians. Or whatever else happens in the wilderness. Sunburn and boredom and stuff.
