Grace Bustill Douglass was born in
Burlington, New Jersey, to the
Bustill family, a well-known abolitionist family. Her father was
Cyrus Bustill, a strong leader in the community and promoter of the abolishment of slavery. Her mother was Elizabeth Morey, who was half Delaware Indian and half English. Douglass was one of eight children; she had three brothers and four sisters. Cyrus Bustill was manumitted before he got married from his
Quaker owner, Thomas Prior, in 1769. In 1803, at the age of 21, Douglass married Robert Douglass, a wealthy barber from
St Kitts in the West Indies, and they had six children together. Not much is known of four of her children, but
Sarah and
Robert Jr. are well documented. Elizabeth was their eldest daughter; she died young after attending a private school for a few years, being forced to leave the school because parents of the white students complained. This led Douglass, along with family friend
James Forten, to open up a school of their own. This school, along with private tutors, was where Sarah, Robert, and their other siblings all received their extensive educations. Sarah went on to become a famous abolitionist and teacher like her mother, and Robert was a well-known portrait painter. ==Anti-slavery activities==
