Step-by-step explanation:
The name that best completes the graphic organizer describing a noted abolitionist, who was born to enslaver parents, converted to Quakerism, and was appalled by the ravages of slavery from an early age is Sarah Grimké. Sarah Grimké and her sister Angelina were the daughters of a wealthy plantation family in South Carolina. They became disgusted with slavery and moved to the North, where they converted to Quakerism, a religion with strong abolitionist sentiments. They became active abolitionists and fought not only for the cause of ending slavery but also for women's rights, which sometimes caused controversy within the abolitionist movement.
