Dulcie May Markham was a prominent Sydney prostitute and associate of gangland figures in Sydney during the 1930s, 1940's and 1950s, when she was closely involved with the razor gang milieu of that era of organised crime within that city. During her criminal career, she had amassed 100 convictions in New South Wales, Victoria, Queensland & Western Australia for prostitution, vagrancy, consorting, assaulting police and the public, keeping a brothel, drunkenness and drunk driving, and was sent to prison on numerous occasions. Dulcie was known in the media as The Angel of Death, The Black Widow and Pretty Dulcie.
Australian pianist and composer Dulcie Holland (1913-2000). There was also an Australian composer called Dulcie Cohen, whose father was a rabbi in Sydney. I'm not sure whether those two Dulcies are in fact one and the same.
