Nina Carmichael was the middle child of William Howland and Margaret Carmichael Howland. Her older brother was named Robert, and her younger sister was named Christine. Like her siblings, Nina was a mulatto child. She had her mother's African American blood flowing through her body, but she most resembled her father. All three children were fair skinned with red hair. Nina was closest in age to her father's granddaughter, Abigail. The two were emotionally close and were childhood playmates. Eventually, Nina was sent away to a Vermont boarding school in an attempt to introduce her to white society.
