It's been revealed that several members of the Suits star's extended family have disturbing histories of drug use, violence, racism, crime and drunken behaviour.
The Markle clan - who originate from Grants Pass, Oregon - hides several black sheep, including Meghan's half-brother Thomas Markle Jr, who was arrested for drunkenly brandishing a gun at his partner Darlene Blount in January.
Now it's further been revealed that despite the altercation, Thomas and Darlene plan to marry in the coming months - meaning Meghan will soon call a drug user associated with white supremacy her brother-in-law.
Darlene's brother Jason Blount was arrested earlier this year for heroin possession and three separate counts of theft.
According to Josephine County Court documents, when police arrived at the scene: 'He was found to be holding a straw with black residue, which he admits was that of heroin...and field [tested] as such.'
In a separate incident on June 5, Jason was caught again for stealing a $60 glass pipe from a garden store - placing the item in his trousers. His accomplice Shawn Kaschak - also a known drug user - was arrested at the scen and as seen in the mugshot, Shawn has a large tattoo emblazened across his neck that is commonly worn by white supremacists, including neo-Nazis and Klu Klux Klan members.
The new shocking revelations about Meghan's extended family have understandably left her 'red-faced' with senior royals, but sources close to the 36-year-old says he won't let it affect her chances of marrying Prince Harry.
