Re: Una Hawken - Bred in Unknown (1972) by N. Murray.

N. Murray was Mrs. Nola Murray of Wanganui, New Zealand. (refer NZ Rose Annual 1970 p88)
Una Hawken also lived at Wanganui, New Zealand (refer NZ Rose Annual 1871 p89)

Probably these two ladies also bred 'Athene', 1975 but I know little about N.Z. roses.
