Yeah not so great, but better than having her younger brother inherit her, I guess. And she actually did a bit better than that (from Wikipedia):

She posthumously freed her slave, Belinda Starling, in her will, wherein she wrote that she, "give[s] and grant[s] to my female slave, Belinda Starling, aged about 26 years, her Freedom at my death; and I also give and bequeath unto said Belinda Starling all the property of which I may die possessed; all which I do to recompense the faithful performance of duties to me."

An attempt at reparation, I guess
