Mitchell was raised as a Quaker in Nantucket, Massachusetts. Her education gave her an academic base, which she was provided as a Quaker, and as a woman of her time, may not have otherwise been respected for. In 1843, at age 25, she left Quakerism to become a Unitarian, as she felt Quakers were becoming too
narrow-minded for her.
