Sarah Marshall was born in Craven County, North Carolina, around 1832. While the exact date is unknown, this period marks the beginning of her life in a region characterized by its complex social and racial dynamics in the pre-Civil War South.

Details of Sarah's childhood are scarce, but growing up in Craven County during this era would have exposed her to the realities of slavery and racial segregation prevalent in the American South. Her early experiences likely shaped her understanding of societal inequalities.

No specific information exists about Sarah Boone's formal education. However, it can be assumed that she likely received limited schooling opportunities typical for African American children in the pre-Civil War South, even those who were free. Family and community probably played a crucial role in her upbringing and development.
