About 12 years after Southey's story was published, writer Joseph Cundall changed the old woman into a little girl in his book "Treasury of Pleasure Books for Young Children". Cundall made this change because there were many children's books about old women at the time. Once the little girl entered the story, she stayed there. She was known over the years as Silverhair, Silverlocks, Goldenlocks, and other names. She finally became Goldilocks sometime in the early 20th century.
