Born: Established: 10 Mar 1936 Melbourne ;
Changed common name from Sowden to Walters. She wrote under the name Sowden between about mid-70s and 1991. From 1996 she has written as Walters. She has another book to be pub'd next year as Walters. As Walters is her birth name and she is using this name again now, I suspect Sowden was her married name and she is no longer married. Can't verify this.
I'm making Walters her common name as this is the name she has written under and appears to be known as since 1996. I'm making Sowden an AKA (rather than alt. writing name) as I don't think its a pseudonym.
