Riistavaara is an adopted name to Finnish from the name Risberg. The name was adopted by Dr. Axel Risberg, who changed his name into the Finnish form of Aksel Riistavaara. The name was ever carried by four persons. His wife Erna, and his children Lars Rafael and Maj-Lis. Unless some of his descendants will adopt the name, it will go down the history as short-lived.
