What is the surname of Anne in the novel "Anne of Green Gables"?

"Anne of Green Gables" is a 1908 novel by Canadian author Lucy Maud Montgomery (published as L. M. Montgomery). Written for all ages, it has been considered a classic children's novel since the mid-20th century. Set in the late 19th century, the novel recounts the adventures of Anne Shirley.

At the age of eleven, Anne was taken from the Hopetown orphanage to the neighbouring province of Prince Edward Island, which she regarded as her true home ever after. Unfortunately, she arrived by mistake, her sponsors, the siblings Matthew and Marilla Cuthbert, wanted to adopt a boy to help them on their farm, but the neighbour with whom they had sent the message was certain they had requested a girl instead.

Matthew quickly became fascinated by the girl's good-hearted spirit, charming enthusiasm, and lively imagination, and wanted her to stay at Green Gables from the very first. Marilla's reaction was to send her back to the orphanage, but she was eventually won over by Anne's exuberant enjoyment of life.
