McKinnon family

McKinnon is the surname of a wizarding family. It is unknown if they were pure-blood or had both magical and Muggle heritage.

The McKinnons were slaughtered by Death Eaters at the height of the First Wizarding War, as they were connected to the Order of the Phoenix. According to Igor Karkaroff, Travers was among those involved. The only known member of this family is the late Marlene McKinnon, who was a member of the Order.

When Lily Potter heard of their deaths, she cried all night.

Etymology
McKinnon is a surname of Scottish origin, anglicised from the Gaelic Mac Fhionghuin, which means "fair born" or "fair son", and can also be translated as "love".

Behind the scenes

 * Other than the Potters and the Longbottoms, Marlene McKinnon is the only former Order member mentioned in the film version of Harry Potter and the Order of the Phoenix.
 * The McKinnons were mentioned in Lily Evans's letter. She stated that Peter Pettigrew had looked sad when he visited, but she believed it was because of what happened to the McKinnons. The Potters and the McKinnons were possibly good friends, as Lily cried when she heard of their deaths.
