The story of the Rajah Quilt would not be possible without Elizabeth Fry. Elizabeth was born in 1780 to a Quaker family. Elizabeth took a great interest in the welfare of others, and after visitng Newgate Prison encouraged others to join her in helping to reform the women in gaols. She began a system of supervision and required the women to sew and to read the Bible. In 1817 she helped found the Association for the Reformation of the Female Prisoners in Newgate. This led to the eventual creation of the British Ladies' Society for Promoting the Reformation of Female Prisoners, widely described by biographers and historians as constituting the first "nationwide" women's organization in Britain.
Grace was one of these convicts. I have no way of knowing if she worked on the quilt, but I like to think she did.
