Abraham Charles Flower (alias Richard Edwards) was transported as a convict to Sarah Island, Macquarie Harbour , Tasmania in 1830. He was one of three convicts converted to Quakerism by Backhouse and Walker. One convict, Henry Propsting, joined the Friends in 1836 and took a prominent part in Quaker activities, another went to Sydney as an assigned servant to James Backhouse, and the third, Flower, after a chequered career was last heard of near Castlemaine in Victoria.
