Shirley J. Yee "Cary, Mary Ann Camberton Shadd," American National Biography Online, February 2000, http://www.anb.org/articles/09/09-00875.html.
Although the eldest of thirteen children, Mary Ann Shadd grew up in comfortable economic circumstances. Little is known about her mother except that she was born in North Carolina in 1806 and was of mixed black and white heritage; whether she was born free or a slave is unknown. Shadd's father was also of mixed-race heritage. His paternal grandfather, Jeremiah Schadd, was a German soldier who had fought in the American Revolution and later married Elizabeth Jackson, a free black woman from Pennsylvania. Abraham Shadd had amassed his wealth as a shoemaker, and his property by the 1830s was valued at $5,000. He was a respected member of the free black community in Wilmington and in West Chester, Pennsylvania, where the family had moved sometime in the 1830s, and he served as a delegate to the American Anti-Slavery Society in 1835 and 1836.
