Margo was the first female member of the Quinntets.
Margo died in the same issue in which she was introduced: Harley Quinn #6. It seems that the fifth spot in Harley Quinn's gang of Quinntets was hard to keep filled. Lester Wilde appeared in only one issue and died. Brad appeared as his replacement in only one issue. Margo appeared as a replacement in only one issue and died.
The only mission Margo took part in as a Quinntet was when Harley Quinn and her crew invaded Wayne Manor, intent on robbing Bruce Wayne. Bad idea.
