His wife inherited some slaves. Quite a few, I think.
No, she inherited none of her fathers slaves upon his death. They remained the property of the estate. They could be held, as slaves, by the executors (Lee was one) until the debts and legacies of the estate were paid off. But they could not be held as slaves any longer than five years after Custis’s death. The last of those slaves was freed about 5 years and a couple of months after his death.
