Sirius Black and Marlene McKinnon is a member of the original Order of the Phoenix.

On the movie version of Order of the Phoenix, Sirius shows Harry a photograph of the original member of the Order.

The first person Sirius mentioned, before James and the others, was Marlene McKinnon.

In the last book, Sirius Black receives a letter from Lily Potter (née Evans) and it mentioned Marlene Mckinnon's passing, which proves that they are indeed friends.

Marlene McKinnon came from a powerful wizarding family, as Hagrid mentioned, "No one ever lived after he decided ter kill 'em... he'd killed some o' the best witches an' wizards of the age — the McKinnons, the Bones, the Prewetts — "

This makes people believe that she is a pure-blood, which makes her similar to Sirius Black.


It is often shown that Marlene McKinnon was in the same year and house as Sirius Black. Which makes Marlene a friend to Lily Potter. It is also shown quite often that Marlene and Sirius had the same personality. reckless and arrogant.

Marlene is described as a tall girl with curly blonde hair. And just like Sirius, she had a lot of admirers during her time at Hogwarts.
