Miller Parker engraved eight illustrations for XXI Welsh Gypsy Folk-Tales, a collection of Welsh Romani stories recorded and translated by John Sampson (1862–1931). Sampson met the Wood family, a dynasty of Welsh Romani musicians, in the 1890s and spent 30 years studying their language and culture. The book was intended to communicate these stories to new audiences and was published in modern English. Miller Parker mostly depicts her figures in 20th-century dress, avoiding the romantic medieval setting often associated with fairy tales.
