I'm fairly confident that she used to go by Liz. I met a 'friend' of Liz' about a year ago in the same flat (was near Walthamstow back then), but other than saying hello, I didn't spend any time with her. She was platinum blonde back then too, I think.
Not much help, I know. But I can verify that she was real. Looked great too.
