Do you know lurline hetherington or lorraine walton former pupils at west ryde primary school australia 1954?

pupils from West Ryde Primary cl 60c 1954 are now in contact via email, newsletter and occasional meetings. Lorraine and Lurline are the only former clmates we have no news of. After West Ryde Lurline went to FortStreet Girls High and after that we believe she became a teacher. Lorraine went to Burwood Girls High and we have no news of her after that.
